摘要
利用不对称相转移催化反应 ,由芳醛或环酮、氯仿和氨合成了 8个光活性α-氨基酸、收率为 2 5 .1 %～ 72 .4% ,比旋光度在± 2 .7～± 5 .
The reaction of chloroform,aromatic aldehydes(or cyclic ketones) and aqueous ammonia in the presence of two chiral phase transfer catalysts and lithium chloride was studied.Eight optical active α amino acids were prepared.The chemical yield was 25.1%～72.4% and the optical rotation is 2.7～5.5°.
