Method for preparing tetrahydropyran derivatives |
| abstract |
A method for preparing a tetrahydropyran derivative having general formula (I) by reducing an epoxy of general formula (II) with a mixture of lithium borohydride and a titanium derivative. In formulae (I) and (II), R1? is an alkyl radical and R2? is an alcohol function protector grouping. In formula (II), R3? is a leaving grouping (methanesulphonyloxy). |
