Disclosed is a method for producing a tetrahydropyran compound represented by general formula (5) shown in the scheme. Accordingly, a tetrahydropyran derivative is obtained in high yield and with high selectivity without using a highly toxic reagent, and an industrially useful method for producing a tetrahydropyran derivative and an intermediate thereof can be provided. In formulae (1) to (5), R 1 and R 2 each independently represent a hydrogen atom, a linear, branched, or cyclic alkyl group, or an aromatic group which may have a substituent, and R 1 and R 2 may be combined to form an alkylene group, thereby forming a ring; and R 3 and R 4 each independently represent a hydrogen atom or a linear, branched, or cyclic alkyl group, and R 3 and R 4 may be combined to form an alkylene group, thereby forming a ring. |
