Asymmetric Synthesis of Amines by Carbon‐Carbon Coupling in the α‐Position to Nitrogen

Abstract

Optically active amines of type (3) and (4) from propargylamine (1) can be obtained by use of the chiral auxiliary compound (S)-(2); the auxiliary compound is recycled in this synthesis. (3) and (4) can be transformed, for example, into amino acids and heterocycles.
