title: Diastereoselective synthesis of substituted tetrahydrothiophenes and -thiopyrans via thia-Prins cyclization reaction.
abstract: Tetrahydrothiophenes and -thiopyrans have been efficiently synthesized from thioacrylates via thia-Prins cyclization reaction mediated by trimethylsilyltrifluoromethanesulfonate with good diastereoselectivity and in good to high yields.
