Abstract: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. Keywords tin powder; glyoxylate ethyl es… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
