Reaction Steps
After adding 7.9 g (0.1 moles) of pyridine and 7.8 g (0.1 moles) of acetyl chloride to 100 ml of dehydrated dimethylformamide and cooling the mixture with ice, 11.3 g (0.05 moles) of stegobiol were dripped and agitated at 20° at 25° C. for 10 hours to provide 12.1 g of 2,3-dihydro-2,3,5-trimethyl-6-(1-methyl-1-acetoxyethyl)-4H-pyran-4-on. The yield was 90%.
