has been developed for the synthesis of 2-substituted tetrahydropyran-4-one derivatives through a condensation of 3-(phenylthio)but-3-en-1-ol with carbonylcompounds in the presence of 5 mol% of Sc(OTf)3 under mild conditions. A few products were subsequently transformed into the corresponding indoles by Fisher-indole synthesis.
