麻烦哪位大仙帮忙翻译一下 （有机胺催化）
|
||
|
中文：由于用非手性的胺催化剂无法得到化合物1a,1b的消旋体，所以这些化合物的消旋体是由构型相反的催化剂得到相应的手性化合物，通过配伍得到的，所以对应异构体的比例难以达到1：1. 大楷就是这么个意思，烦请各位师兄师姐帮忙翻译一下。 谢谢了。 |

| As the racemic of the 1a and 1b compounds couldn`t be obtained by using the non-chiral amide catalyst, the racemic of the those compounds was synthesised by the coordinated reaction of the related chiral compounds and the catalytic effect of the reversed structure compounds , so the equivalent of the enantimoer couldn`t reach 1:1 . |

| Because using achiral amine catalyst can 't get compound 1 a and 1 b of racemic form, so these compounds of racemic form is by configuration opposite catalyst get corresponding chiral compounds, through the compatibility get, so it is difficult to achieve corresponding isomer proportion of 1:1. |
