摘要

采用格氏试剂对a-氨基氧基-2-烯基硼酸盐和α-氨基氧基-烷基硼酸盐进行处理，合成了高度富集对映体的仲醇。中间硼酸盐配合物通过引入残基的迁移立体定向转化为相应的2-烯基和烷基硼酸盐。氧化检查得到了富集对映体的仲醇。

Stereospecific Reaction of α-Carbamoyloxy-2-alkenylboronates and α-Carbamoyloxy-alkylboronates with Grignard Reagents - Synthesis of Highly Enantioenriched Secondary Alcohols

Highly enantioenriched secondary alcohols were synthesized by treatment of a-carbamoyloxy-2-alkenylboronates and α-carbamoyloxy-alkylboronates with Grignard reagents. An intermediary boronate complex was transformed stereospecifically to the corresponding secondary 2-alkenyl- and alkylboronates by migration of an introduced residue. Oxidative workup furnished the enantioenriched secondary alcohols.
