Thiazolidine-Tetrahydrothiazine in the Thiadiazabicyclooctanone System

The interconversion of thiazolidine-tetrahydrothiazine in some derivatives if thiadiazabicyclooctane in aqueous HCl has been studied. In the case of 6- and 7-substituted hydroxy or methoxy thiadiazabicyclooctanone a reversible rearrangement was found. The sulfoxide of thiadiazabicyclooctanone under the same reaction conditions undergoes epimerisations, while reaction with fosforpentachloride-via a corrseponding sulfenyl chloride-affords a mixture of 6- and 7-substituted hydroxy or metoxy derivatives of thiadiazabicyclooctanone.
