  Convenient method for the preparation of 1-phenylthio-3-alken-1-ynes and 4-hydroxy-1-phenylthio-1,2-alkadienes from a common precursor

  摘要：

  4-Hydroxy-1-phenylthio-2-alkynes (5) reacted with dihydropyran to afford the corresponding 4-tetrahydropyranyloxy derivatives which, on treatment with KHMDS, gave a mixture of (E)- and (Z)-1-phenylthio-3-alken-1-ynes, with the former predominant. When MeLi was used in the place of KHMDS, the (Z)-isomers were formed in preference to the (E)-isomers. Further treatment of the mixture with a base converted the (Z)-isomers into (E)-isomers. On the other hand, the reaction of 5 with KHMDS gave the corresponding 4-hydroxy-1-phenythio-1,2-alkadienes. (C) 2002 Elsevier Science Ltd. All rights reserved.

  八元和九元环状烯丙基ulf化萘的σ重排中的立体选择性。乙烯基取代的丁内酯和戊内酯的合成

  摘要：

  （）-4-苯甲硫基-2-丁烯-1-醇衍生物6的铑（II）乙酸铑催化的[2,3]σ-重排重氮丙二酸酯提供了高度立体选择性的乙烯基取代的丁内酯10以这种方式，虽然重排同系物的重氮丙二酸酯，但（）-5-苯硫基-3-戊烯-1-醇衍生物9产生了乙烯基取代的戊内酯13和14，前者占优势。发现使用9中的立体化学固定的取代基R是导致后面的重排中的高立体选择性的重要因素，如通过使用重氮丙二酸酯20b作为底物所显示的。

• A Highly Regioselective Reaction of Allylic Acetates with Silylated Carbon Nucleophiles Directed by a Sulfenyl Group. Scope, Limitation, and Mechanistic Aspects

  α-(Sulfenylmethyl)allyl acetates reacted with silylated carbon nucleophiles in the presence of a catalytic amount of TMSOTf to give products substituted at the α-position of the sulfenylmethyl group in moderate to good yields with high regioselectivity. The theoretical calculation on an intermediate cationic species indicated that an episulfonium ion was a stable form; the observed regioselectivity was rationalized qualitatively on the basis of the coefficients of LUMO of the cation. Some transformations of the products were also demonstrated.

  α-(Sulfenyl甲基)烯丙基醋酸盐在催化量的TMSOTf存在下，与硅烷化的碳亲核试剂反应，以中等至良好的产率和高度区域选择性在硫代甲基的α-位置上进行取代。对中间体阳离子物种的理论计算表明，环硫鎓离子是一种稳定形式；观察到的区域选择性定性地基于阳离子的LUMO系数进行合理化。还展示了一些产物的转化。
