    • A novel process makes it possible to produce optically active amines of the formula (I*) in which R and R have the meanings given in the description, by reacting a) in a first step, racemic amines of the formula (I) with esters of the formula (II), in which R and R have the meanings given in the description, in the presence of hydrolases and possibly a diluent, b) in a second step, the mixture obtained is separated into (S) amine of the formula (I-S) and acylated (R) amine of the formula (III) and c) optionally in a third step (R) amine of the formula (I-R) is released from acylated (R) amine of the formula (III) by treatment with an acid or base, possibly in the presence of a diluent. Acylated (R) amines of the formula (IIIa) in which R , R , R , X and p have the meanings given in the description.
    • 根据本发明的新方法,该式表示的光学活性胺(I *),其中R和R <1>的,由一)外消旋在第一步骤中制备的,式(I)与所述的含义的胺在描述中所指示 式的酯(Ⅱ),其中R <3>和R <4>具有说明书中给出的含义,如果合适的话在水解酶在稀释剂的存在下存在,b)中在第二阶段所得到的混合物(S) 式的胺(IS)和酰化(R)式(III)的胺是分开的,以及c)任选地在第三阶段从酰化(R)式(III)的胺通过用酸处理或碱,任选地在 稀释剂(R)式(IR)释放 - 胺的存在下进行。 式(IIIa)的酰化的(R) - 胺,其中R <11>,R <12>,R <13>,X和p具有在说明书中给出的含义。
