REACTION OF ETHYL N-CYANOMETHYLBENZEHECARBOXIMIDATE WITH ALIPHATIC ALDEHYDES UNDER THE SOLID-LIQUID PHASE TRANSFER CATALYSIS

摘要

Ethyl N-cyanomethytbenzenecarboximidate reacted with aliphaticaldehydes under the solid-liquid PTC condition to gire a-ethoxyphenylmethylene-aminoacrylonitrile derivatives and oxazoline derivatives.It is a convenientand new method for synthesis of β,β’-dihyroxy-a-amino acids by hydrolysis ofthe oxazoline derivatives.
