Synthesis of Hexahydroindol-6-ones by Cycloacylation of Vinylogous Urethanes

The title compounds were prepared by variations of a route in which the principal stages include conversion of N-substituted pyrrolidine-2-thiones 6 into vinylogous urethanes 10, which undergo subsequent cycloacylation.A related approach that uses a Robin
