✦ Synopsis
In a previous communication' we described base-catalyzed rearrangement of the imino chloride 1 of penicillin V methyl ester to oxazole 9. In the work described herein we report formation of novel B-lactam 8 which arises, after a complicated series of steps, from the interaction of 1 with ketene 3.
