Tetrahydrofuran → 1-o-Benzyl-3-o-t-butyldimethylsilyl-2-o-methyl-rac-glycerol

Participants

Reaction Steps

Alcohol Compound 40 (48.8 g, 0.16 mmol) was added to a mixture of NaH (4.0 g, 0.17 mol) in dry THF (500 mL). After 5 min, Mel (10 mL, 0.17 mol) was added and, after another 3 hours, the mixture was quenched with H2O (150 mL), extracted into diethyl ether (500 mL), dried (MgSO4) and concentrated. Purification of the residue by silica-gel column chromatography [eluent: hexane/ethyl acetate, 90/10, v/v] yielded 1-O-benzyl-3-O-t-butyldimethylsilyl-2-O-methyl-rac-glycerol (Compound 41) (37 g, 74%) as a yellow oil.
