The invention provides a method for enantioselectively reducing a prochiral carbon centred radical having one or more electron donor groups attached directly to the central prochiral carbon atom of the radical, and/or attached to a carbon atom within 1 to 4 atoms of the central prochiral carbon atom, comprising treating said radical with an activated chiral non-racemic organosilicon hydride in the presence of a Lewis acid. The invention also provides a novel class of activated chiral non-racemic organosilicon hydrides.
该发明提供了一种用于对一个或多个电子给体基固定在该自由基的中心手性碳原子上,和/或固定在与中心手性碳原子相距1至4个原子的碳原子上的一个具有手性选择性还原的手性碳中心自由基的方法,包括在存在Lewis酸的情况下,用活化的手性非消旋有机
硅氢化物处理所述自由基。该发明还提供了一种新型的活化手性非消旋有机
硅氢化合物类。
