  Synthesis, spectral, crystal and antimicrobial studies of biologically potent oxime ethers of nitrogen, oxygen and sulfur heterocycles

  摘要：

  Three series of oxime ethers viz, 2,6-diarylpiperidin-4-one O-benzyloximes 5a-o, 2,6-diaryltetrahydropyran-4-one O-benzyloximes 7a-e and 2,6-diaryltetrahydrothiopyran-4-one O-benzyloximes 11a-b and 12a-c were synthesized and stereochemistry is established by their spectral and single crystal analysis. A SAR study has been carried out for the above oxime ethers against a panel of antibacterial (Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi and Escherichia coli) and antifungal agents (Candida albicans, Candida-51, Rhizopus sp., Aspergillus niger, Aspergillus flavus and Cryptococcus neoformans), respectively, using Ciprofloxacin and Amphotericin B as standards. Most of the chloro/methyl/methoxy substituted compounds exerted moderate to good activity against all the tested organisms; moreover, some compounds (5i, 5l, 5n, 5o, 7c2, 7d1, 7d2, 7e, 11b and 12c) exhibited promising activity than standard drugs.

• Diastereoselective Synthesis of 2,6-Diaryltetrahydrothiopyran-4-ones by Phase-Transfer Catalysis

  Two efficient phase-transfer-catalyzed protocols for the diastereoselective synthesis of cis and trans isomers of 2,6-diaryltetrahydrothiopyran-4-ones (2,6-DATHTPs) have been developed. In a study of the scope of the reactions, differently substituted 2,6-DATHTPs were successfully accessed in high yields and diastereomeric excessses on both experimental and preparative scales.

  已经开发了两种有效的相转移催化方案，用于非对映选择性合成 2,6-二芳基四氢噻喃-4-酮 (2,6-DATHTPs) 的顺式和反式异构体。在对反应范围的研究中，不同取代的 2,6-DATHTP 在实验和制备规模上均以高产率和非对映体过量成功获得。
• Spectral characterization and crystal structure of some 2,6-diarylthian-4-one hydrazone derivatives

  A series of cis and trans 2,6-diarylthian-4-one hydrazone derivatives (11-16) have been synthesized and characterized by H-1, C-13 and two dimensional NMR spectroscopy. For the 2r,6t-diphenylthian-4-one N-isonicotinoylhydrazone (14) X-ray diffraction have also been recorded. The coupling constants suggested that the cis-hydrazones (11-13), which have the phenyl groups in cis orientation, largely exist in chair conformations with equatorial orientation of the phenyl groups 11C. Analysis of the vicinal coupling constants of trans-hydrazones (14-16) suggests that boat forms 14B must make significant contributions to it and the relative population is 58%. Moreover, in solution chair conformations 14C and 14C', may contribute to 14. The NOESY and X-ray diffraction of 14 gives definite evidence for the contribution of 14C. (C) 2014 Elsevier B.V.
