1.02 g (7 mmol) of glucal, 0.5-0.7 ml of H2O and about 2 g of crushed molecular sieves are taken up in 25-50 ml of isopropenyl acetate, and 1 g of lipase from Pseudomonas spec. is added and the mixture is stirred at room temperature for 25-30 h. Filtration and concentration in vacuo are followed by chromatography on silica gel (ethyl acetate/hexane 2:3, v:v). 0.97-1.05 g (60-65%) of 3,6-di-O-acetylglucal are obtained.
