Abstract

Dihydropyridones derived from the aza-Diels–Alder reaction of 3-phenylthio-3-sulfolenes with p-toluenesulfonyl isocyanate (PTSI) gave readily the epoxy sulfones, which upon treatment with base afforded the 2-pyrido-fused bicyclic compounds. Some synthetic transformations of these compounds are also reported.
