AN ALTERNATIVE SYNTHESIS OF THE 1-OXACEPHEM SKELETON

1-Oxacephem skeletons were constructed in a convergent manner starting from building blocks B and C, which were easily prepared from penicillin and diketene, respectively, followed by intramolecular carbene insertion reaction of the resulting intermediate
