Diversity-Oriented Stereocontrolled Synthesis of Some Piperidine- and Azepane-Based Fluorine-Containing beta-Amino Acid Derivatives

Structural diversity-oriented synthesis of some azaheterocyclic beta-amino acid derivatives has been accomplished by selective functionalization of readily available cyclodienes. The stereocontrolled synthetic concept was based on the oxidative ring cleavage of unsaturated cyclic beta-amino acids derived from cycloalkadiene, followed by ring closing with double reductive amination, which furnished some conformationally restricted beta-amino acid derivatives with a piperidine or azepane core.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 2403-88-5. Computed Properties of C9H19NO.

Immunostimulating properties of the azaheterocyclic compounds BIV-3, BIV-4, BIV-7

In animals and humans, immune system performs an important function to maintain the constancy of the body internal environment, carried out by recognizing and eliminating alien substances of antigenic nature from the body. This immune system function is carried out with the congenital and acquired immunity factors. Different types of radiation, heavy metal salts, vitamin and micronutrient deficiency, stressful situations, age-related changes in the lympho-myeloid complex, therapy with anti-tuberculosis, antibacterial, hormonal, cytostatic drugs and a number of other factors lead to the development of immune diseases. These diseases can be treated with a set of immunotherapy methods; use of immunostimulants is one of them. Today, immunostimulants are distinguished as of microbial, thymic, bone marrow, cytokine, nucleic, plant and synthetic origin. Azaheterocyclic compounds comprise a class of compounds that have demonstrated significant biological activities against various human diseases. We suggest that azaheterocyclic compounds with a piperidine nucleus are perspective for the search for new effective immunostimulating drugs. To study their immunostimulating activity, the following compounds were taken: BIV-3 – 1-(3-butoxypropyl)-3-methylpiperidine 4-spiro 5′-imidazolidine-2′,4′-dione, BIV-4 – 1-(2-ethoxyethyl)-4-hydroxy-4-dimethoxyphosphorylpipericline, BIV-7 – complex of 3-(2-morpholinoethyl)-7-(3-isopropoxypropyl)-3,7-diazabicyclo [3.3.1] nonane with beta-cyclodextrin. The comparison drug was methyluracil. Results of the studies are presented in this paper.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 477600-74-1, you can contact me at any time and look forward to more communication.

Silacyclohexanes, Sila(hetero)cyclohexanes and Related Compounds: Structure and Conformational Analysis

Conformational analysis of Si-mono- and Si,Si-disubstituted silacyclohexanes as well as their analogues with a heteroatom(s) in the ring is reviewed with the focus on the recent results. Experimental measurements in the gas phase (gas electron diffraction, GED) and low temperature NMR spectroscopy (LT NMR) on H-1, C-13 and Si-29 nuclei are described along with theoretical calculations at the DFT and MP2 levels of theory. Structural and conformational specific features are shown to be principally different from those of the carbon predecessors-the corresponding cyclohexanes, oxanes, thianes and piperidines. The role of various effects (steric, hyperconjugation, stereoelectronic, electrostatic) is demonstrated.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 4727-72-4. Application In Synthesis of 1-Benzylpiperidin-4-ol.

Proline-Catalyzed Asymmetric -Amination in the Synthesis of Bioactive Molecules

The direct -amination of carbonyl compounds using organocatalysts represents a powerful and atom-economical tool for asymmetric C-N bond formation. We describe a complete account of -functionalization of carbonyl compounds, through iterative sequential -aminoxylation/amination using electrophilic O and N sources, as well as sequential -amination/HWE reaction for enantio- and diastereoselective synthesis of both syn – and anti -1,3-aminoalcohols and 1,3-diamines. Additionally this protocol is further extended for the easy construction of alkaloids such as indolizidine, pyrrolizidine, and quinolizidine fused-ring systems just by tuning the chain length of the aldehyde used as a starting material. This methodology provides further scope to extrapolate it for a variety of naturally occurring hydroxylated monocyclic and fused bicyclic pyrrolidine and piperidine based alkaloids such as lentiginosine, epi -lentiginosine, dihydroxypyrrolizidine, (+)-deoxoprosophylline and (-)-deoxoprosopinine alkaloids. Furthermore, we have also uncovered proline-catalyzed anti -selectivity for the synthesis of 1,2-amino alcohols in -amination of aldehyde and one-pot indium-mediated Barbier type allylation of -hydrazino aldehydes to accomplish the total synthesis of clavaminols, sphinganine and spisulosine with reduced number of steps and with high overall yields. 1 Introduction 2 Application in the Total Synthesis of Alkaloids 3 Conclusion

QSAR and Molecular Docking Studies on Non-Imidazole-Based Histamine H-3 Receptor Antagonists

Background: In the recent years, histamine H-3 receptor (H3R) has been receiving increasing attention in pharmacotherapy of neurological disorders. ‘the aim of the current study was to investigate structural requirements for the prediction of H-3 antagonistic activity using quantitative structure-activity relationship (QSAR) and molecular docking techniques. Methods: To this end, genetic algorithm coupled partial least square and stepwise multiple linear regression methods were employed for developing a QSAR model. The obtained QSAR model was stringently assessed using different validation criteria. Results: The generated model indicated that connectivity information and mean absolute charge are two important descriptors for the prediction of H-3 antagonistic activity of the studied compounds. To gain insight into the mechanism of interaction between studied molecules and H3R, molecular docking was performed. The most important residues involved in the ligand-receptor interactions were identified. Conclusion: The result of current study can be used for designing of new H(3 )antagonist and proposing structural modifications to improve H-3 inhibitory potency.

Synthesis, crystal and solution structures of platinacyclic complexes containing eugenol, the main bioactive constituent of Ocimum sanctum L. oil

The dinuclear platinacyclic complex [Pt2Cl2(Eug-1H)(2)] (1) (Eug-1H = deprotonated eugenol) has been synthesized. Reaction of 1 with amines afforded [PtCl(Eug-1H)(pyridine)] (2), [PtCl(Eug-1H)(4-Me-pyridine)] (3), [PtCl(Eug-1H)(piperidine)] (4), [PtCl(Eug-1H)(quinoline)] (5), [PtCl(Eug-1H)(NH3)] (6), [PtCl(Eug-1H)(4-Me-aniline)] (7), [PtCl(Eug-1H)(4-Cl-aniline)] (8), [Pt(Eug-1H)(8-O-quinoline)] (9) and [Pt(Eug-1H)(8-O-2-Me-quinoline)] (10). X-ray diffraction and NMR analysis show that in complexes 1-10 the chelating eugenol ligand is bound with the Pt(II) ion both through the ethylenic double bond of the allyl group and at a benzene carbon atom; in 2-10 the donor N atom of the amine is in the cis-position with respect to the ethylenic double bond. For complexes 2 and 3, two types of relatively strong highly directional intermolecular interactions are observed in the crystal packing: O-H center dot center dot center dot ClPt(II) hydrogen bonds and C-H center dot center dot center dot pi interactions, in 3 further complemented by C-H center dot center dot center dot Cl interactions. The crystal packing of 7 is dominated by dimer formation through O-H center dot center dot center dot O, N-H center dot center dot center dot Cl, C-H center dot center dot center dot Cl and C-H center dot center dot center dot pi interactions. In a d-chloroform solution of 2-5 two types of strong intermolecular interactions were detected: a Cl3C-D center dot center dot center dot ClPt(II) hydrogen bond and Cl2DC-Cl center dot center dot center dot Pt(II) halogen bond.

Efficient and Eco-Friendly One-Pot Synthesis of Functionalized Furan-2-one, Pyrrol-2-one, and Tetrahydropyridine Using Lemon Juice as a Biodegradable Catalyst

New and facile one-pot approach for the syntheses of polysubstituted pyrrol-2-one, furan-2-one and tetrahydropyridines (THPDs) from easily available starting materials using lemon juice as a green catalyst is presented. The synthesis of diverse furan-2-one and pyrrol-2-one derivatives were achieved from dialkyl acetylenedicarboxylates, different amines and aldehydes in high yields and short reaction times by employing 0.25 mL of lemon juice at 110 C-degrees under solvent-free condition. THPDs, on the other hand, were synthesized via the reaction among beta-ketoesters, various aromatic aldehydes, and amines in the presence of 0.25 mL of lemon juice in ethanol at room temperature. The molecular structure of compound pyrrol-2-one 7e and THPD 10 g were confirmed by the single crystal X-ray analysis. Application of cheap and green catalyst, environmentally benign reaction condition, good to high yields, applicable to a broad range of substrates and no column chromatographic separation are some salient features of this protocol.
