Abstract

As organozinc reagents are essentially unreactive toward ester carbonyl groups,@-hydroxy esters have been prepared conveniently via the Reformatsky reaction, wherein a-halo esters react with aldehydes and ketones in the presence of zinc.'However, the direct synthesis of@- keto esters via the Reformatsky reaction with esters and other carboxylic acid derivatives has never been reported, owing to this property of organozinc compounds. Recently it was ...
