Novel 2-substituted thiazoline azetidinones are obtained from 2,6-disubstituted thiazoline azetidinones by ozonolysis and solvolysis. Reduction of the 2-substituted thiazoline azetidinones by treatment with aluminum amalgam or sodium borohydride leads to the corresponding thiazolidine azethidinones. The latter class of compounds are useful in the synthesis of penicillins and cephalosporins. |
