| Abstract: |
Shows two simple, efficient and complementary methods for the regiospecific C4-epimerization of cis-4-formyl-2-azetidinones. Use of aqueous dimethylamine as reagent in heterogeneous medium with benzene; Presence of benzyltributylammonium bromide as the phase-transfer catalyst; Novel base-promoted rearrangement of the beta-lactam ring to cyclic enaminones. |
