反応手順

BH3.SMe2 (17 mL, 1 M in THF) was added slowly to a stirred solution of 2-(benzyloxymethyl)-3,4-dihydro-2H-pyran (2.87 g, 14.06 mmol) (13) in THF (100 mL) at −78° C. The resulting mixture was allowed to warm to room temperature overnight. The mixture was quenched by the slow addition of 1M NaOH (50 mL) at 0° C. followed by H2O2 (13 mL, 30% in water). The resulting mixture was stirred for 2 hours at room temperature. After aqueous work up the residue was purified on silica gel using EtOAc and hexane to give 6-(benzyloxymethyl)tetrahydro-2H-pyran-3-ol (14).
