Optically active cyclic amines of the formula (I) or salts thereof
in which A, R
0
, R are each as defined in claim 1, and R
0
and A, or R and A, or R
0
and R may also form rings,
where R and the NH—R
0
group on the two ring carbon atoms marked with an asterisk (*) in each case are arranged in cis arrangement to one another and the stereochemical configuration on these carbon atoms is different from the racemic configuration, can be prepared effectively by a process, which comprises converting an imine (a racemic imine) of the formula (II)
in which A, R
0
and R are each as defined in formula (I), in the presence of hydrogen or a hydrogen donor and a nonenzymatic catalyst which comprises a catalytically active optically active complex of one or more transition metals from the group of ruthenium, rhodium, palladium, iridium, osmium, platinum, iron, nickel and samarium with organic ligands, to the compound of the formula (I).
公式(I)或其盐的光学活性环状胺,其中A,R0,R的定义如权利要求1所述,且R0和A,或R和A,或R0和R也可以形成环,其中R和在每种情况下标有星号(*)的两个环碳原子上的NH—R0基团彼此以顺式排列,并且这些碳原子上的立体化学构型与外消旋构型不同,可以通过以下方法有效地制备,该方法包括在氢或氢供体和非酶催化剂的存在下,将公式(II)的亚胺(外消旋亚胺)转化为公式(I)的化合物,其中A,R0和R的定义如公式(I)所述,所述非酶催化剂包括来自钌,铑,钯,铱,锇,铂,铁,镍和钐的过渡金属中的一个或多个的催化活性光学活性配合物和有机配体。
