An efficientsynthesis of 2,3-disubstituted tetrahydropyransfrom aldehyde and cyclopropyl alkenol has been accomplished using HBF4·OEt2 as a promoter through a tandem vinylcyclopropane ring-opening/Prinscyclization. It is a convenient process to generate a structurally diverse and biologically relevant 2,3-disubstituted tetrahydropyrans in good yields with high selectivity.
