Abstract

Cis 2,6-Diphenyltetrahydrothiapyranone (1) was subjected to Wittig reaction to generate exocyclic double bond (2a-c). Cycloaddition of nitrile oxides and nitrile imines to the latter led to a novel spiro tetrahydrothiapyranoisoxazolines (3a-f) and spiro tetrahydrothiapyranopyrazolines (4a-f)
