Abstract
Cycloaddition reactions of 2,5-di-tert-butylthiophene S-oxide and 2,3,4,5-tetrakis(p-tolyl)thiophene S-oxide with alkenes are described. The reactivity of 2,5-di-tert-butylthiophene S-oxide as diene in Diels–Alder reactions is compared with 2,5-di-tert-butylthiophene S,S-dioxide. The thermal and photochemical SO extrusion reactions of the cycloadducts under formation of highly substitutedaromatic compounds are exemplified.
