Abstract

Abstract The copper salt-catalyzed interaction of ethyl diazopyruvate with ketones, aldehydes and nitriles was examined. A variety of 1, 3-dioxoles and oxazoles was obtained in moderate yield. The formation of enol ethers, epoxides, carbon-carbon insertion products, aziridines, and azetidines, typical products of carbene reactions with carbon-heteroatom multiple bonds, was not observed. Evidence for the operation of a 1, 3-dipolar ...
