Abstract

Abstract A simple route is described for the synthesis of E and Z 3??chloro??2??propenamides (4a??e), esters (3a) and acids (2a??c) by the reaction of 2, 3??acetylenic acids with oxalyl chloride in DMF followed by treatment of the corresponding 3??chloro??2??propenoyl chloride derivative with amines, alcohol and water.
