Sodium borohydride → HCID 121396372, compound

Participants

Reaction Steps

To a stirred solution of 1-[(3aR,5S,6aR)-2,2-dimethyl-3a,5,6,6a-tetrahydrofuro[2,3-d][1,3]dioxol-5-yl]-2-methoxy-ethanone (compound 21c, 1.4 g, 6.5 mmol) in methanol (50 mL) was added sodium borohydride (494 mg, 13 mmol). After being stirred at room temperature for 2 hours, the resulting solution was quenched by saturated NH4Cl solution and concentrated in vacuo. The residue was suspended in EtOAc and then filtered. The filtrate was concentrated in vacuo to afford 1.24 g of crude product of 1-[(3aR,5S,6aR)-2,2-dimethyl-3a,5,6,6a-tetrahydrofuro[2,3-d][1,3]dioxol-5-yl]-2-methoxy-ethanol (compound 21d) as a colorless oil. MS obsd. (ESI+) [(M+NH4)+]: 236.
