by Strecker-type reactions from chiral CF3 imines and iminium proved to be very attractive versatile intermediates for the synthesis of various α-trifluoromethyl amino compounds. From these synthons, both enantiomers of α-trifluoromethyl alanine, trifluoromethyl 1,2-diamines, and amino alcohols were conveniently obtained in enantiopure form in high yields in a few steps.
通过Strecker型反应从手性CF 3亚胺和亚胺盐获得的非对映异构纯α-三氟甲基α-氨基腈被证明是用于合成各种α-三氟甲基氨基化合物的非常有吸引力的通用中间体。从这些合成子中,可以通过几个步骤方便地以高纯度得到对映纯形式的α-三氟甲基丙氨酸的对映异构体,三氟甲基1,2-二胺和氨基醇。
