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.
根据一种新的工艺,可以通过在
水存在下,pH值在3.0至10.0之间,温度在0℃至80℃之间,可选地在有机稀释剂的存在下,使用适于分解式(II)中N-酰胺的(R)-对映体的
脂肪酶,反应式(II)中R.sup.1、R.sup.2、R.sup.3和n具有所述描述中给出的含义的N-酰胺,来制备式(1)中R.sup.1、R.sup.2和n具有所述描述中给出的含义的(R)-胺。
