Synthesis of fluspidine via asymmetric NaBH4 reduction of silicon enolates of beta-keto esters

Asymmetric NaBH4 reduction catalyzed by the Co(II) complex of a chiral diamidine-type sp(2)N ligand, Naph-diPIM-dioxo-iPr, was successfully applied to 3-silyloxycinnamate substrates without over-reduction, giving quantitatively 3-silyloxy-3-arylpropionates with an enantiomer ratio of up to 99:1. The high utility was confirmed on a 30-g scale using 0.1 mol% catalyst. Both Z and E substrates could be converted to a single enantiomeric product by changing the ligand chirality. The relationship between the ZIE stereochemistry and the absolute configuration of the 1,4-reduction product provided important information about the mechanism underlying enantioface selection. Combination of the asymmetric catalysis with two other key steps, Suzuki coupling with an N-protected tetrahydropyridine boronic acid derivative and intramolecular bromo etherification, realized an efficient synthetic route to both enan-tiomers of fluspidine. The new strategy permits the introduction of substituents on the two aryl groups and piperidine ring, allowing for structural variations toward the development of higher performance sigma 1 receptor antagonists.

Synthesis, spectral characterization, DFT studies and biological activity of novel Ligand 1-(2-cyclohexyl thioethyl) piperidine and its complexes with group 12 metal chlorides

C-6 H11S-Na+ (generated insitu by reaction of NaOH with C6H11SH) on treatment with 1-(2-chloroethyl) piperidine hydrochloride under N-2 atmosphere resulted in (1-(2-cyclohexyl thioethyl) piperidine) (L-1) as orange solid. It’s complexes having the formula [ZnCl2. L-1] (1), [CdC1(2). (L I )] (2) and [HgC1(2). L-1] (3) have been prepared. L-1 and its complexes 1-3 were characterized on the basis of physico-chemical and spectral (FT-IR, Mass, H-1, C-13 and DEPT 135 degrees NMR) studies. Powder XRD diffraction pattern reveals the crystalline nature of L-1 and complex 1. Complexes 1-3 adopt distorted tetrahedral geometry showing bidentate mode of coordination through S and N. Using DFT-based optimization of structures, the HOMO-LUMO energy gaps and molecular electrostatic potential maps (EPM) of compound L-1 and complexes 1-3 were theoretically calculated at the B3LYP/6-311G (d, p) level of theory. HOMO-LUMO energy gap was calculated which allowed the calculation of relative properties like chemical hardness, chemical inertness, chemical potential, nucleophilicity and electrophillicity index of the synthesized products. The experimentally obtained IR and NMR results showed a good correlation with those of the theoretical ones. Ligand L-1 and complexes 1-3 display significant antibacterial and antifungal activity.

Synthesis, spectroscopic characterization, DFT studies and biological activity of bis (1-(ethyl) piperidine) diselenide (L) and its complexes with selected group 12 metal halides

Se-2(2) (generated insitu by NaBH4 reduction of Se) on reaction with 1-(2-chloroethyl) piperidine hydrochloride under N-2 atmosphere resulted in bis(1-(ethyl) piperidine) diselenide (L) as an orange solid. It’s bimetallic complexes having the formula [Zn2Cl4L] (1), [Cd2Cl4L] (2) and [Cd2Br4L] (3) were also synthesized. L and its complexes 1-3 were characterized on the basis of physico-chemical and spectral (FT-IR, Mass, H-1, C-13, DEPT and Se-77 NMR) studies. IR spectroscopy revealed that M (II) ions (zinc and cadmium) are coordinated through selenium and nitrogen forming a five membered ring around M (II) ions. Elemental analysis measurement along with H-1, C-13, DEPT and ESI mass data confirmed the tetradentate mode of coordination of the ligand L. Moreover the coordination from selenium atom is also supported by the downfield shift of signal in Se-77 NMR spectroscopy. Powder XRD diffraction pattern reveals the crystalline nature of Ligand L and complexes 1-3. Heteroditopic ligand L (N, Se, Se, N) ligates through both selenium and nitrogen atoms to two respective metal halides in complexes 1-3, thus forming bimetallic complexes. Using DFT-based optimization of structures, the HOMO-LUMO energy gaps and molecular electrostatic potential surface of ligand L and complexes 1-3 were theoretically calculated at the B3LYP/LANL2DZ level of theory. These complexes adopt distorted tetrahedral geometry around M(II) ions as revealed by bond angles. HOMO-LUMO energy gap was calculated which allowed the calculation of relative properties like chemical hardness, chemical inertness, chemical potential, nucleophilicity and electrophilicity index of the synthesized products. The experimentally obtained IR and NMR results showed a good correlation with those of the theoretical ones. Ligand L and complex 1-3 displayed significant antibacterial and antifungal activity.

Chemical Profiling of Lobelia chinensis with High-Performance Liquid Chromatography/Quadrupole Time-of-Flight Mass Spectrometry (HPLC/Q-TOF MS) Reveals Absence of Lobeline in the Herb

Lobelia chinensis is a kind of herbal medicine widely distributed and used in Asia. The chemical components of this herb, however, have not been well studied until now. Lobeline, as an essential and famous bioactive compound in Lobelia genus, has been assumed to be present in L. chinensis. In order to ascertain its presence and, more importantly, proper use of this herb, chemical profiling this herb with highly sensitive and high-resolution analytical mass spectrometry was applied. In this study, high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (HPLC/Q-TOF MS) method was employed to systematically profile the chemical constituents of L. chinensis for the first time. Comparative chemical profiling study of L. chinensis and Lobelia inflata was also conducted to provide evidence whether lobeline is present or not. Piperidine alkaloids except for lobeline, alkaloid-lignan hybrids, flavonoids, polyacetylenes, nonanedioic acid, and some new phytochemicals were successfully identified in L. chinensis simultaneously. Comparing to the chemical profiles of L. inflata, lobeline was found to be absent in L. chinensis. All of the secondary metabolites in L. chinensis were determined with the HPLC/Q-TOF MS method. The absence of lobeline in L. chinensis was confirmed after this extensive study.

Piperidine-induced Switching of the direct band gaps of Ag(i)/Bi(iii) bimetallic iodide double perovskites

The environmental toxicity of lead may eventually hamper the wide applications of hybrid perovskite material-based solar cells despite their excellent power conversion efficiency. Here, we have used silver(i) and bismuth(iii) to replace lead(II) and obtain two two-dimensional (2D) iodide-based double perovskites, (AMP)(4)[BiAgI8](2)center dot H2O (1) and (APP)(4)[BiAgI8]center dot H2O (2), where AMP = 4-aminomethylpiperidine and APP = 4-aminopiperidine. Compared to our previously reported 1,4-cyclohexanediamine-based compound (C6H16N2)(2)[BiAgI8]center dot H2O with an indirect band gap, these two new 2D Ag-Bi double perovskites show direct band gaps (similar to 2.00 eV) due to the less distorted [AgI6] coordination geometry. Moreover, the photo-current response experiments showed a difference of more than 50 nA between light and dark conditions for both the compounds, indicating the potential application for light harvesting.1and2were also stable under heat and moisture. They showed high proton conductivity (similar to 10(-4)S cm(-1)) at 95 degrees C and 90% RH. Thus, this work provides a new route for designing stable lead-free bimetallic iodide double perovskites with direct band gaps.

Synthesis and Kinetics of Highly Substituted Piperidines in the Presence of Tartaric Acid as a Catalyst

Aim & Scope: The synthesis of highly substituted piperidine from the one-pot reaction between aromatic aldehydes, anilines and beta -ketoesters in the presence of tartaric acid as a catalyst has been investigated in both methanol and ethanol media at ambient temperature. Different conditions of temperature and solvent were employed for calculating the thermodynamic parameters and obtaining an experimental approach to the kinetics and mechanism. Experiments were carried out under different temperature and solvent conditions. Material and Methods: Products were characterized by comparison of physical data with authentic samples and spectroscopic data (IR and NMR). Rate constants are presented as an average of several kinetic runs (at least 6-10) and are reproducible within +/- 3%. The overall rate of reaction is followed by monitoring the absorbance changes of the products versus time on a Varian (Model Cary Bio-300) UV-vis spectrophotometer with a 10 mm light-path cell. Results: The best result was achieved in the presence of 0.075 g (0.1 M) of catalyst and 5 mL methanol at ambient temperature. When the reaction was carried out under solvent-free conditions, the product was obtained in a moderate yield (25%). Methanol was optimized as a desirable solvent in the synthesis of piperidine, nevertheless, ethanol in a kinetic investigation had none effect on the enhancement of the reaction rate than methanol. Based on the spectral data, the overall order of the reaction followed the second order kinetics. The results showed that the first step of the reaction mechanism is a rate determining step. Conclusion: The use of tartaric acid has many advantages such as mild reaction conditions, simple and readily available precursors and inexpensive catalyst. The proposed mechanism was confirmed by experimental results and a steady state approximation.

Density functional theory study on the dehydrogenation of 1,2-dimethyl cyclohexane and 2-methyl piperidine on Pd and Pt catalysts

Liquid organic hydrogen carrier (LOHC) is one of the advantageous hydrogen storage technologies, which store hydrogen through a chemical bond in liquid organic compounds. We previously developed a promising LOHC material, 2-[N-methylbenzyl]pyridine (MBP). However, the mechanism and catalytic behavior for the dehydrogenation of dodecahydro-MBP (H-12-MBP) on the catalysts are not still clear. For the fundamental understanding of H-12-MBP dehydrogenation, we focused on the two main fragments of H-12-MBP that are 1,2-dimethyl cyclohexane (DCH) and 2-methyl piperidine (MPD). Density functional theory (DFT) calculations were performed to investigate their catalytic dehydrogenation on Pd(111) and Pt(111). In order to compare the catalytic activities, the reaction energy profiles for DCH and MPD on both surfaces were calculated. By identifying the rate-determining steps, it was found that Pd had higher (lower) catalytic activity for MPD (DCH) than Pt. The different dehydrogenation sequences on Pd(111) and Pt(111) due to the different preference of bond formation for pi and sigma, respectively can be one of the origins for the different catalytic activities between the two catalysts.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 5570-77-4. The above is the message from the blog manager. Recommanded Product: 4-Chloro-1-methylpiperidine.

Identification of inhibitor against H. pylori HtrA protease using structure-based virtual screening and molecular dynamics simulations approaches

The HtrA protease of Helicobacter pylori, which efficiently colonizes at the gastric epithelial of host cells, disrupts the mucosal integrity of E-cadherin and spreads inflammatory diseases including gastric cancer by cleaving the cell-cell adhesion of the host. The lack of knowledge on the molecular diversity, structural and functional behavior of HpHtrA necessitated the present study to explore its inhibition mechanism. At first, the similarity of HpHtrA with other gastro-intestinal pathogenic HtrA bacteria and its remote relationship with the Human HtrA homologs were ensured by the phylogenetic analysis and hence was identified as a novel therapeutic target for further design of inhibitors. The three dimensional structure of HpHtrA was modeled and simulated to achieve its stable conformation and was used as a receptor to screen for the possible lead compound through virtual screening (using similar to 1.3 million compounds). Molecular dynamics simulations followed by the binding energy analysis revealed the affinity of the compound 300040 in forming a stable complex with HpHtrA and thereby revealed its potent role in inhibiting HpHtrA. It is also worthy to mention that, structurally, the ligand binding at the catalytic site of HpHtrA is mainly facilitated by the significant dynamics of L2 loop. Based on the present study, the hydroxyl-piperidine with 4-aminopiperidine scaffold is proposed to be one of the best possible lead compounds for the inhibition of H. pylori.
