An efficient method has been developed for the synthesis of 2,3-dihydropyrans and 4-methylenetetrahydropyrans from aldehydes and substituted homoallyl alcohols in benzene mediated by boron trifluoride etherate in good yields. The reaction proceeds via oxonium-ene reaction.

2-Aryl-4-methyl-4,5-epoxytetrahydropyrans, which react with piperidine regioselectively with trans-diaxial cleavage of the oxide ring at the least substituted carbon atom, were synthesized by the reaction of 2-aryl-4-methyl-3,6-dihydropyrans with peracids.
