The addition of allylmagnesium chloride to the chiral, non-racemic α,β-epoxyimine (2) is highly diastereoselective, and the facial selectivity can be controlled by the use of BF3.OEt2; Addition of vinylmagnesium bromide in the presence of this Lewis acid also takes place with high diastereoselectivity.
向手性,非外消旋的α,β-环氧亚胺(2)中添加烯丙基氯化镁具有很高的非对映选择性,并且可以通过使用BF 3 .OEt 2来控制面部选择性。在该路易斯酸的存在下,乙烯基溴化镁的添加也具有非对映选择性高。
