An efficient synthesis of dihydro- and tetrahydropyrans viaoxonium–ene cyclization reaction

Abstract

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 viaoxonium–ene reaction.
