A 3-acyl-2-(N-cyanoimino)oxazolidine derivative was found to serve as an en
antioselective acylating agent for sec-alkyl amines. These reagents differe
ntiate the enantiomers of 1-phenylethylamine derivatives up to 85% ee, and
the recovered chiral auxiliary is reusable. (C) 2001 Elsevier Science Ltd.
