Disclosed are cis-2,6-disubstituted tetrahydropyran derivatives represented by Chemical Formula 1 and a preparation method thereof. The tetrahydropyran derivatives can be prepared by Prins-reacting tetrahydropyran derivatives with homopargylicalcohol derivatives in the presence of trimethylsilyltriflate. The tetrahydropyran derivatives with cis-substituents at both C2 and C6 positions of the tetrahydropyran ring are useful as intermediates for use in the synthesis and development of therapeutically effective, naturally occurring compounds.
(wherein, R
