The highly Lewis basic amidine-based catalyst DHIP promotes the rearrangement of S-phenacyl thiocinnamate and related thioesters into dihydrothiophene derivatives. In contrast to previously explored rearrangements of thioesters, the reaction proceeds

Several additional examples of cascade cyclizations of α,β-unsaturated thioesters proceeding are reported, which proceed via two distinct mechanistic pathways: enantioselective acyl transfer promoted by amidine-based catalysts (ABCs) and a racemic
