by Strecker-type reactions from chiral CF3 imines and iminium proved to be very attractive versatileintermediates 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.
