The present invention relates to a method of enantioselective addition to imines, including: reacting R
3
CH═NY with R
4
ZnR
5
in the presence of a compound represented by the following formula (I),
in which Y, R
1
, R
2
, R
3
, R
4
and R
5
are defined the same as the specification. Accordingly, the present invention can prepare secondary amines in high yields and enantiomeric excess by the above-mentioned method.
本发明涉及一种对
亚胺进行对映选择性加成的方法,包括:在以下式(I)所代表的化合物存在下,将R3CH═NY与R4ZnR5反应,其中Y、R1、R2、R3、R4和R5的定义与规范相同。因此,本发明可以通过上述方法高产率和对映过量地制备二级胺。
