    摘要: In accordance with a novel process, (R)-amines of the formula ##STR1## in which R.sup.1, R.sup.2 and n have the meanings given in the description, can be prepared by reacting reating N-acyl-amines of the formula ##STR2## in which R.sup.1, R.sup.2, R.sup.3 and n have the meanings given in the description,with lipases which are suitable for cleaving the (R)-enantiomers of N-acyl-amines of the formula (II), in the presence of water and optionally in the presence of an organic diluent, at a pH of between 3.0 and 10.0 and at temperatures of between 0.degree. C. and 80.degree. C.
