Reactivity of Stable Trifluoroacetaldehyde Hemiaminals. 2. Generation and Synthetic Potentialities of Fluorinated Iminiums
摘要:
Under Lewis acid activation, hemiaminals of trifluoroacetaldehyde and related (fluoroalkyl)-aldehydes generate iminium species that can react with various nucleophiles to provide fluorinated amines.

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.
