探索了锡粉促进下,乙醛酸乙酯、酰肼和烯丙基溴的“一锅法”反应.各种酰肼都能参与反应并以高产率生成α-酰肼基-γ-戊烯酸乙酯.当异戊烯基溴和巴豆基溴代替烯丙基溴反应时,得到的都是γ-加成产物.该反应提供了一种合成α-酰肼基-γ-戊烯酸酯化合物的新方法.

An one-pot reaction of glyoxylate ethyl ester, acylhydrazines and allyl bromide promoted by tin powder has been developed. The reaction has been investigated using different acylhydrazines leading to allylic α-acylhydrazino esters in very high yield. When allyl bromide was replaced with prenyl bromide or crotyl bromide to perform the reaction, the γ-addition products were obtained. The reaction provides a new approach for the synthesis of allylic α-acylhydrazino esters.

Key words: tin powder, glyoxylate ethyl ester, acylhydrazines, one pot reaction, allylic α-acylhydrazino esters
