Abstract
A cyclopropane/butyrolactone derivative 2-methoxy-4-oxo-3-oxa-bicyclo[3. 1. 0]hexane-6,6-dicarboxylate was synthesized through Michael addition,internal nucleophilic substitution reaction of 5-methoxy-2( 5H)-furanone and bromomalonic acid diethyl ester. The structure of the title compound was confirmed through1 H NMR、13C NMR and X-ray single crystal diffraction.
