Reaction Steps

Pyridinium p-toluenesulfonate (50 mg) was added to a solution of 8.3 g of (R)-methyl glycerate in 30 ml of 2,2-dimethoxypropane and the mixture was refluxed for 30 minutes. The reaction mixture was purified by columnchromatography using silica gel (120 g) and hexane:ethyl acetate (5:1) as an eluant to give 9.87 g (89%) of (R)-methyl glycerate acetonide.
