PROCEDURE

实验过程

1.0 g (4 mmol) of 6-O-benzoylglucal is taken up in 10-20 ml of vinyl acetate and stirred with 1 g of lipase (Pseudomonas spec.) at room temperature for 5 h. Filtering off the enzyme and crystallization or chromatography on silica gel (ethyl acetate/hexane 1:1) yields 3-O-acetyl-6-O-benzoylglucal in 88-94% yield (1.03-1.10 g).
