Abstract

A simple and efficient approach for the synthesis of privileged oxime esters by employing donor-acceptor cyclopropane diesters (DACs) as one of the potential precursors is reported. The strategy involves Lewis acid catalyzed ring-opening of DACs, resulting in an open-chain intermediate followed by the base-mediated construction of the corresponding oxime esters in a one-pot reaction. Moreover, the process also features the synthesis of diethyl 4-(4-methoxyphenyl)azete-2,2(3H)-dicarboxylate.
