Reaktionsschritte

A mixture of 23 g of enzyme lipase "Amano" CES (produced by Amano Pharmaceutical Co., Ltd), 40 g of (R,S)-1-tetrahydropyranyloxy-2-butanol and 16.5 g of vinyl caproate was reacted with stirring at 38° C. for eight hours. After the reaction was stopped, the enzyme was removed by filtration, and the enzyme on the filter paper was washed by using n-heptane. n-Heptane was distilled away from the filtrate, the residue was purified with a chromatograph over silical gel, and 21.5 g of optically active 1-tetrahydropyranyloxy-2-butanol and 23 g of 1-tetrahydropyranyloxy-2-caproyloxybutane were obtained.
