関与物質

反応手順

The compound obtained in Step B (13.4 mmol) and osmium tetroxide (0.16 mmol) are dissolved in 70 ml of a mixture of tetrahydrofuran/water (1/1). Sodium periodate (26.9 mmol) is added in small portions and the reaction mixture is stirred for 2 hours at ambient temperature. The reaction mixture is poured into 50 ml of 5% sodium hydrogen carbonate solution, the insoluble material is filtered off and the aqueous phase is extracted twice with 75 ml of ether. The organic phase is washed with water, decolourised and evaporated. The precipitate obtained is recrystallised from cyclohexane and yields the title product in the form of a white solid.
