Bi(OTf)(3)–, TfOH–, and TMSOTf–Mediated, One-Pot Epoxide Rearrangement, Addition and Intramolecular Silyl-Modified Sakurai (ISMS) Cascade Toward Dihydropyrans: Comparison of Catalysts and Role of Bi(OTf)(3)

Catalytic quantities of bismuth(III) triflate efficiently initiate the rearrangement of epoxides to aldehydes which subsequently react with (Z)-δ-hydroxyalkenylsilanes to afford 2,6-disubstituted-3,6-dihydro-2H-pyrans. Isolated yields of desired products using Bi(OTf)(3) were compared with yields wh...
