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 of the radical, said method comprising generating said radical from a radical precursor compound and reacting said radical with a chiral non-racemic organotin hydride in the presence of a Lewis acid and a co-reducing agent, wherein said co-reducing agent is capable of regenerating chiral non-racemic organotin hydride without substantially reducing said radical or said radical precursor compound.
该发明提供了一种对具有一个或多个直接连接到基本手性碳原子上的电子给体基团的原始手性碳中心自由基进行对映选择性还原的方法,以及/或连接到基本手性碳原子附近1到4个原子的碳原子上的电子给体基团的原始手性碳中心自由基,所述方法包括从自由基前体化合物生成所述自由基,并在存在Lewis酸和共还原剂的情况下将所述自由基与手性非消旋
有机锡氢化合物反应,其中所述共还原剂能够再生手性非消旋
有机锡氢化合物,而不显著还原所述自由基或所述自由基前体化合物。
