A PROCESS FOR PREPARING CHIRAL (S)-2,3-DISUBSTITUTED-1-PROPYLAMINE DERIVATIVES

A process for the preparation of chiral (S)-2,3-disubstituted-1-propylamine derivatives, in which a carbonyl group of (S) 3,4-disubstituted-1-butanecarbonyl derivatives is converted to an amine group, and the conversion reaction is performed through Curtius rearrangement or Hoffman rearrangement.
