| Product | 3-O-acetyl-6-O-benzoylgalactal | HCID 14308115 | 80% |
Reaction Steps
1.0 g (4 mmol) of 6-O-benzoylgalactal is taken up in 10-15 ml of dimethoxyethane (DME) and 20-25 ml of vinyl acetate and stirred with 1 g of lipase P at room temperature for 8 h, Filtering off the enzyme and crystallization or chromatography on silica gel (ether/hexane 1:1) yield 3-O-acetyl-6-O-benzoylgalactal in 80-85% yield,
