実験手順

The procedure of Example 5 (i) was repeated except that vinyl valerate was used instead of 2,2,2-trichloroethyl butyrate to give 10.4 g of S-form of 1-(4-(tetrahydro-2-pyranyloxy)phenyl)ethanol (yield: 94%) and 13.9 g of R-form of 1-(4-tetrahydro-2-pyranyloxy)phenyl)ethyl valerate (yield: 91%).
