  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。

  Enantioenriched indenes were reached through a chirality conversion strategy using original axially chiral benzylidene cyclanes. Good to high remote diastereocontrol and excellent enantiocontrol were observed in this cascade involving copper-catalyzed homologation of terminal alkynes, in situ allenoate formation and Alder-ene cyclization.

  通过使用原始的轴向手性亚苄基环戊烷的手性转化策略可达到对映体富集的茚满。在该级联反应中观察到了良好的远程非对映异构控制和优异的对映异构控制，包括末端炔烃的铜催化同源化，原位烯酸酯形成和Alder-ene环化。

  The rates of oxime formation of 41 heterocyclic ketones have been measured at 5 °C in aqueous alcoholic solution buffered at pH 6.85. The data indicate an overall second-order reaction, first order each in ketone and hydroxylamine. In all cases investigated the reaction appears to be irreversible under the experimental conditions employed. Increased steric retardation is observed as steric crowding

  已在5°C的pH值为6.85的酒精水溶液中测定了41种杂环酮的肟形成速率。数据表明总体为二级反应，一级反应分别为酮和羟胺。在所研究的所有情况下，该反应在所采用的实验条件下似乎都是不可逆的。随着在羰基官能团周围的空间拥挤的增加，观察到增加的空间延迟，这表明发生了确定胺基对羰基基团的速率的攻击。4-哌啶酮，oxan-4-ones，thian-4-ones，相应的1,1-dioxides和selenan-4-ones肟的形成速率有显着差异。
• Syntheses of 4H-Thiopyran-4-one 1,1-Dioxides as Precursors to Sulfone-Containing Analogs of Tetracyanoquinodimethane

  Synthetic routes to the unsubstituted 4H-thiopyran-4-one 1,1-dioxide (5a), 2,6-dialkyl-substituted, 2-aryl- or 2-heteroaryl-6-alkyl-substituted, 2,6-diaryl- or diheteroaryl-substituted, and 2-heteroaryl-6-aryl-substituted 4H-thiopyran-4-one 1,1-dioxides 5b-s are described. Sodium hydrosulfide hydrate in buffered aqueous alcohol can be used as a substitute for hydrogen sulfide gas for the introduction of sulfur to methyl acrylate, to 1,5-disubstituted-1,4-pentadien-3-ones 13, or to 1,5-disubstituted-1,4-pentadiyn-3-ones 17. The double dehydrogenation af 2,3,5,6-tetrahydrothiopyran-4-one 1,1-dioxides 13 with iodine-DMSO-sulfuric acid gives thiopyran-4-one 1,1-dioxides 5 in good yield and small amounts of 1,4-pentadien-3-ones 13. 2,3,5,6-Tetrahydrothiopyran-4-one 1,1-dioxide (9) and 5,6-dihydrothiopyran-4-one 1,1-dioxide (12), which lack aryl or heteroaryl substituents, give poor yields of 4H-thiopyran-4-one 1,1-dioxide (5a) with iodine-DMSO-sulfuric acid.

  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.
