反応手順

To a mixture of 3 g 4-hydroxy-decanoic acid 3,7-dimethyl-oct-6-enyl ester and 1.45 g pyridine in 7 ml tetrahydrofuran was slowly added a solution of 1.87 g chlorocarbonic acid phenethyl ester (Schiving et al., Bull. Soc. Chim. Fr. (4), 43, 1928, 858) in 7 ml tetrahydrofuran. The mixture was stirred for 16 hours. Water was added and the mixture extracted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, 2N hydrochloric acid, water, dried over magnesium sulfate and evaporated to dryness. The residue was chromatographed on silica gel to give 3.91 g of a colorless liquid.
