Abstract

The present invention provides a novel process for producing known optically active amines and optically active acylated amines by: PA1 a) in a first step, reacting racemic amines with esters, in the presence of hydrolases and possibly a diluent; PA1 b) in a second step, separating the reaction mixture into (S)-amine and acylated (R)-amine; and c) optionally in a third step releasing (R)-amine from acylated PA1 (R)-amine by treatment with an acid or base, possibly in the presence of a diluent. The optically active amines can be employed as intermediates for preparing pharmaceuticals and crop protection agents.
