unsaturated aldehydes 2 from variously substituted silylated vinyloxiranes is achieved with the aid of palladium(0) catalysis under smooth experimental conditions. One example of a versatile application of this rearrangement reaction, in the case of the tert-butyldimethyl(3-vinyloxiran-2-yl)silane derivative 1a, has resulted in one-pot diastereoselective syntheses of the highly functionalized polysubstituted
在平稳的实验条件下,借助钯 (0) 催化,从各种取代的甲硅烷基化乙烯基环氧乙烷中立体选择性地制备 α-甲硅烷基化 α-季不饱和醛 2。这种重排反应的通用应用的一个例子,在叔丁基二甲基(3-乙烯基环氧乙烷-2-基)硅烷衍生物 1a 的情况下,导致了高度官能化的多取代 δ-内酯 33-的一锅非对映选择性合成39,已经研究了其反应性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
