Diastereoselective conversion of chiral imines of the formula I to amines of the formula II
where the R
1
to R
4
radicals are each as defined in the description and R
1
and R
2
are different than one another, by converting the imine of the formula I in the presence of hydrogen and a heterogeneous copper-containing catalyst.
对式I的手性
亚胺进行不对映选择性转化,生成式II的胺,其中R1到R4基团如描述中所定义,且R1和R2不同,通过在
氢气和含
铜杂质催化剂的存在下将式I的
亚胺转化。
