Preparation and study of spirocyclic cationic side chain functionalized polybiphenyl piperidine anion exchange membrane

Research on the ion conductivity and mechanical stability of anion exchange membranes (AEMs) has achieved great progress, it is more urgent to prepare AEMs with high alkali stability. Azaspimcyclic cations are among the most alkali-stable cations. In this study, a synthesized long-chain 3-(3-(1-(8-bromooctyl) piperidin-4-yl) propyl)-6-azaspiro [5.5] undecan-6-ium bromide(BOP-ASU) cation was introduced into a portion of a piperidine ring on a PBP backbone to prepare PBP-BOP-ASU, and AEMs based on PBP-ASU and PBP-BOP-ASU were prepared. The structure of each product was characterized (1H NMR, MS), and the prepared anion exchange membrane was also characterized using micromorphology (SEM, TEM, AFM) and performance tests (TGA, WU, SR, ion conductivity, alkali stability). The PBP-BOP-ASU (8% membrane) showed the highest ion conductivity (117.43 mS/cm) at 80 degrees C. In addition, it showed excellent alkali stability in a test environment of 2 M NaOH solution at 80 degrees C for 1400 h. Moreover, the introduction of side chain spiro cations could improve the microscopic phase separation structure of the AEMs, and it also increased their ionic conductivity, thus ensuring the potential for their application in anion exchange membrane fuel cells.

(-)-Cytisine: Access to a stereochemically defined and functionally flexible piperidine scaffold

N-Benzyl cytisine undergoes an efficient C(6)-N(7) cleavage via directed C(6) lithiation, borylation and oxidation to provide a ‘privileged’ heterocyclic core unit comprising a highly functionalised, cis-3,5-disubstituted piperidine in enantiomerically pure form. The potential offered by this unit as a means to explore chemical space has been evaluated and methods have been defined (and illustrated) that allow for selective manipulation of N(1), C(3′), and the pyridone N. The pyridone core can also be diversified via bromination (at C(3 ”) and C(5 ”)) which is complementary to direct C-H activation based on Ir-catalyzed borylation to provide access to C(4 ”). The use of a boronate-based 1,2-migration as an alternative trigger to mediate C(6)-N(7) cleavage of cytisine was evaluated but failed. However, the stability of the intermediate boronate opens a new pathway for the elaboration of cytisine itself using both Matteson homologation and Zweifel olefination.

Synthesis and Study of 1-Alkenyl-2-propargyloxy-3-aminomethylbenzenes as Acid Corrosion Inhibitors and Antimicrobial Additives to Cutting Fluids

A series of polyfunctional organic compounds, 1-propenyl- and 1-allyl-2-propargyloxy-3-aminomethylbenzenes containing simultaneously an aminomethyl group and fragments with C=C and C equivalent to C bonds, were prepared in high yield (77.6-94%) by Mannich ternary condensation of 2-propenyl- and 2-allylphenols and their p-methyl-substituted derivatives with formaldehyde and secondary amines (diethylamine, piperidine, and morpholine), followed by the reaction of the products with propargyl bromide. The structures of the compounds were confirmed by the NMR spectra. The compounds were studied as inhibitors of acid corrosion of St3 steel and as antimicrobial additives to cutting fluids. 1-Propenyl-2-propargyloxy-3-diethylaminomethylbenzene showed the highest protective performance. At its concentration of 0.01 and 0.05 g L-1, the degree of corrosion protection of St3 steel in 0.5 M H2SO4 was 92.0 and 99.6% (at 25 degrees C) and 70.0 and 98.7% (at 60 degrees C), respectively. 1-Propenyl- and 1-allyl-2-propargyloxy-3-aminomethylbenzenes (in 0.25-1% concentrations) showed only bactericidal properties, whereas the p-methyl-substituted derivative, 1-methyl-3-allyl-4-propargyloxy-5-morpholinomethylbenzene, showed high bactericidal and fungicidal properties simultaneously. 1-Propenyl- and 1-allyl-2-propargyloxy-3-aminomethylbenzenes surpass the known antimicrobial additive, 8-hydroxyquinoline, in the bactericidal performance at identical concentrations, and 1-methyl-3-allyl-4-propargyloxy-5-morpholinomethylbenzene surpasses it in both bactericidal and fungicidal performance.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 4727-72-4, you can contact me at any time and look forward to more communication. Quality Control of 1-Benzylpiperidin-4-ol.

1,8-Diazabicyclo [5.4.0]undec-7-ene Catalyzed Synthesis of Some New 7-Alkyl-6-oxo-1H-pyrazolo[3,4-b]pyridine-5-carbonitriles

Starting from 5-chloro-1,3-diphenyl-1H-pyrazole-4-carbaldehyde, the synthesis of some new bicyclic 7-alkyl-6-oxo-1,3-diphenyl-6,7-dihydro-1H-pyrazolo[3,4-b]pyridine-5-carbonitriles catalyzed by 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) is described. Knoevenagel condensation reaction of 5-chloro-1, 3-diphenyl-1H-pyrazole-4-carbaldehyde with ethyl cyanoacetate in refluxing ethanol containing a few drops of piperidine afforded the (Z)-ethyl 3-(5-chloro-1,3-diphenyl-1H-pyrazol-4-yl)-2-cyanoacrylate. Treatment of this compound with primary alkyl amines in the presence of DBU as a catalyst in dimethylformamide at reflux temperature gave new 7-alkyl-6-oxo-1,3-diphenyl-6,7-dihydro-1H-pyrazolo[3,4-b]pyridine-5-carbonitriles in high yields. All synthetic compounds were characterized on the basis of their spectral and microanalytical data. The correct stereoisomer of the Knoevenagel product was confirmed with comparison of the experimental and calculated H-1 nuclear magnetic resonance (NMR) and C-13 NMR chemical shifts using density functional theory calculations at the B3LYP/6-31+G(d,p) level of theory.

Field-induced slow magnetic relaxation in low-spin S=1/2 mononuclear osmium(v) complexes

Photochemical reactions of (PPh4)[Os-VI(N)(L)(CN)(3)] (NO2-OsN) with piperidine and pyrrolidine afforded two osmium(v) hydrazido compounds, (PPh4)[Os-V(L)(CN)(3)(NNC5H10)] ([PPh4]1) and (PPh4)[Os-V(L)(CN)(3)(NNC4H8)] ([PPh4]2), respectively. Their structures consist of isolated, mononuclear distorted octahedral osmium anions that are well-separated from each other by PPh4+. Their low spin S = 1/2 and L = 1 ground state was confirmed by magnetometry and DFT calculations. Interestingly, both compounds exhibit slow magnetic relaxation under a bias dc-field. These osmium(v) complexes are potentially useful building-blocks for the construction of molecule-based architectures with interesting magnetic properties. In contrast, the structurally related (PPh4)[Os-III(L)(CN)(3)(NH3)] ([PPh4]3), which also has a low-spin S = 1/2 ground state but with a different electronic configuration (5d(5)), does not exhibit slow magnetic relaxation, due to the absence of any orbital moment (L = 0). Furthermore, the structurally different osmium(v) hydrazido compound reported by Meyer, [Os-V(tpy)(Cl)(2)(NNC5H10)](PF6) (4[PF6]), also does not exhibit slow magnetic relaxation due possibly to a change in magnetic anisotropy from axial for [PPh4]1 and [PPh4]2 to planar.

A common strategy towards the synthesis of 1,4-dideoxy-1,4-imino-L-xylitol, deacetyl (+)-anisomycin and amino-substituted piperidine iminosugars

A strategy towards the synthesis of three different target molecules, namely 1,4-dideoxy-1,4-imino-L-xylitol, deacetyl (+)-anisomycin and amino-substituted piperidine iminosugars, molecules of potential biological and medicinal significance, is reported from a common amino-vicinal diol intermediate derived from tri-O-benzyl-D-glucal. Construction of the key pyrrolidine ring present in 1,4-dideoxy-1,4-imino-L-xylitol and (+)-anisomycin was a consequence of thermodynamically driven concomitant intramolecular nucleophilic addition reaction of the amino group to the resultant aldehyde obtained by oxidative cleavage of the amino-vicinal diol. Alternatively, double nucleophilic substitution on an amino-diol, after mesylation, with various amines delivered amino-substituted piperidine iminosugars in good yields.

Autocombustion-Promoted Synthesis of Lanthanum Iron Oxide: Application as Heterogeneous Catalyst for Synthesis of Piperidines, Substituted Amines and Light-Assisted Degradations

An autocombustion technique was adopted to synthesize the Perovskite structured Lanthanum iron oxide nanoparticles (LaFeO3, abbreviated as LFO NPs). This technique offered lots of benefits such as short reaction time along with quick heating rate. LFO NPs were fabricated at different calcination temperatures (300-800 degrees C) through the aid of sucrose as chelating agent. The prepared LFO NPs were well characterized by various techniques like X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Vibrating sample magnetometer (VSM), Ultraviolet-Visible spectroscopy (UV-Vis), Brunauer-Emmett-Teller (BET), X-ray Photo-Electron Spectroscopy (XPS) and Transmission electron microscopy (TEM) which affirmed that highly crystalline LFO NPs were obtained at 700 degrees C. Subsequently, the catalytic activity of the LFO NPs was surveyed for three independent approaches: (i) for the synthesis of functionalized piperidines through activation of carbonyl groups in the reacting partners (ii) for the sunlight-assisted mineralization of health hazardous food colorant, Allura Red AC (iii) for the hydrogenation of nitro aromatic compounds (NACs) using NaBH4(sodium borohydride) as source of hydrogen in aqueous medium at room temperature.

Octahydrocyclopenta[c]pyridine Scaffold – Enantioselective Synthesis and Indole Annulation

An optically active hexahydrocyclopenta[c]pyridine derivative with quaternary stereocenter was prepared as a new heterocyclic scaffold. Key reaction was the Pd-catalyzed asymmetric allylic alkylation of a piperidine-based beta-oxoester, which proceeded in very good yield with high level of enantioselectivity (90 %, 95 % ee). The a-allyl moiety was transformed into a 1,4-diketone by Pd-catalyzed Wacker oxidation with molecular oxygen (89 %). This intermediate was cyclized in an intramolecular aldol reaction furnishing the cyclopentenone motif (86 %). Hydrogenation of the C-C double bond gave the cisannulated octahydrocyclopenta[c]pyridine (86 %), which was submitted to Fischer indolization (85 %). Although two regioisomers could be expected, only the angular constitution was observed. Relative and absolute configurations were established by X-ray crystallography of a para-iodo benzamide derivative. The utility of the title compound as scaffold is further highlighted by a number of synthetically useful transformations, for instance formation of carboxamides, sulfonamides, ureas and reductive aminations with aldehydes.
