  Iodine as a mild and efficient catalyst for the diastereoselective synthesis of δ-silyloxy-γ-lactones

  摘要：

  Aldehydes undergo smooth nucleophilic addition with 2-trimethylsilyloxyfuran in the presence of 10 mol % of iodine under mild and neutral conditions to produce the corresponding 6-silyloxy-alpha,beta-unsaturated-gamma-lactones in high yields and with moderate diastereoselectivity. ortho-Substituted benzaldehydes afford the syn-isomer predominantly. The use of iodine makes this procedure quite simple, more convenient and cost-effective. (C) 2008 Published by Elsevier Ltd.

• Catalysis of Mukaiyama Aldol Reactions by a Tricyclic Aluminum Alkoxide Lewis Acid
  作者：Steven M. Raders、John G. Verkade

  日期：2009.8.7

  The Mukayiama aldol reaction of aldehydes is efficiently accomplished with a low concentration of the dimeric alumatrane catalyst 2 at mild or subambient temperatures. Our protocol tolerates a wide variety of electron-rich, neutral, and deficient aryl, alkyl, and heterocyclic aldehydes. A wide variety of enol silyl ethers are also tolerated. An intermediate that was isolated provides mechanistic information

  在温和或低于室温的温度下，用低浓度的二聚体金刚烷催化剂2有效地完成了醛的Mukayiama醛醇缩醛反应。我们的协议可以耐受多种富电子，中性和不足的芳基，烷基和杂环醛。也可以耐受各种各样的烯醇甲硅烷基醚。分离出的中间体提供了有关二聚体2在Mukaiyama aldol反应中的作用的机械信息。实验证据表明，与F 3 B相比，路易斯酸的5酸更强。

  日期：——

  The direct aldol reaction of γ-crotonolactone and various aromatic aldehydes is catalyzed by bifunctional aminothiourea and aminosquaramide organocatalysts to provide diastereomerically and enantiomerically enriched 5-substituted 2(5H) furanones (γ-butenolides). The reaction is a simple alternative to the classical vinylogous aldol reaction of silyloxy furans.
