An atom-economic route to thiophenes and 2,2'-bithiophenes by intramolecular transannulation of gem-dialkylthio enynes.
An atom-economic route to thiophenes and bithiophenes has been developed starting from the readily available gem-dialkylthio enynes. A range of functionalized thiophenes and bithiophenes, bearing a pendent vinylthio group, were obtained in good to high yields under mild conditions.
