Method for producing tetrahydropyran compound and intermediate thereof

摘要

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), R1 and R2 each independently represent a hydrogen atom, a linear, branched, or cyclic alkyl group, or an aromatic group which may have a substituent, and R1 and R2 may be combined to form an alkylene group, thereby forming a ring; and R3 and R4 each independently represent a hydrogen atom or a linear, branched, or cyclic alkyl group, and R3 and R4 may be combined to form an alkylene group, thereby forming a ring.;

1. A compound represented by the structural formula (3)wherein R1 and R2 independently represent a hydrogen atom, a linear, branched or cyclic alkyl group, or an aromatic group that may has a substituent group, provided that R1 and R2 may be joined to form an alkylene group thereby forming a ring, and R3 and R4 independently represent a hydrogen atom or a linear, branched or cyclic alkyl group, provided that R3 and R4 may be joined to form an alkylene group thereby forming a ring.
