Studies related to Penicillins. Part 20. The Mechanism of the Rearangement of Methyl Benzylpenicillinate to Methyl Benzylpenillonate

In boiling benzene containing a trace of iodine, methyl benzylpenicillinate (1) isomerises to methyl benzylpenillonate (10a).The rearrangement is triggered by a 4,7-bond cleavage of the penicillinate (1a) and probably involves the formation of methyl (4S)
