Abstract Several stereoselective routes to the synthesis of (1S,3R)-t-butyldimethyl-(1-methyl-3-oxiranyl-propoxy)-silane ( 13a ) were explored, and the use of Jacobsen's hydrolytic kinetic resolution to separate a mixture of diastereomeric epoxides was a key step in the shortest of these. As part of an approach to the total synthesis of amphidinolide T2 ( 2 ), this epoxide, corresponding to C17–C22
摘要 探索了几种立体选择性合成 (1S,3R)-t-丁基二甲基-(1-methyl-3-oxiranyl-propoxy)-硅烷 ( 13a ) 的路线,并利用 Jacobsen 的水解动力学拆分分离了非对映体环氧化物是其中最短的一个关键步骤。作为氨苯环内酯 T2 (2) 全合成方法的一部分,该环氧化物对应于天然产物的 C17-C22,通过镍催化的还原偶联反应成功地与炔烃 (C13-C16) 结合.
