反応手順
To a mixture of 19 g (0.05 mol) of cholesta-1,4,6-trien-3-one (I), 6.8 g (0.05 mol) of potassium acid sulphate and 200 g (2 mol) of isopropenyl acetate were added 200 ml of butyl acetate, and the resulting mixture was heated under reflux for 7 hours. After completion of the reaction, the same treatment as in Example 1 was carried out to yield 11.1 g of cholesta-1,5,7-trien-3-ol (IV). The yield was 58%.
