ChemInform Abstract Selective cleavage of thiazolidines such as (I) is carried out in MeCN with CaCO3 as acid scavenger. Although the non-halogenated species give good yields of the acetates (III), the halogenated ones show low reactivities. Somewhat higher yields are obtained using AcOH as solvent.

Reaction of the penam (I) with phenyl(trichloromethyl)mercury (II) results in ring cleavage and alkylation, producing the unsaturated ester (III).
