Reaction Steps

To a solution of 0.5 g of (4R,6S)-6-(dimethoxymethyl)-4-hydroxy-tetrahydropyran-2-one (II′) in 50 mL of dichloromethane, 280 mg of imidazole are added at 25° C. After cooling to 0° C., 400 mg of tert-butyldimethylsilyl chloride are added. The reaction mixture is then stirred for 18 hours and dichloromethane is distilled off. The residue is flash chromatographed (DIPE/acetonitrile=5/1). The solvents are distilled off to get the title compound.
