Abstract
A simple and efficient method for the synthesis of trans-3-substituted 4-formyl-2-azetidinones 2 is described based on the regiospecific C4- epimerization of the cis-isomers 1 using aqueous dimethylamine as reag ent in heterogeneous medium. (C) 1998 Elsevier Science Ltd. All rights reserved.
