反応手順

12.5 ml (24.15 mmol) of a 20% solution of phosgene in toluene are cooled in an ice-bath, a solution of 1.06 g (12.03 mmol) of (R)-(+)-3-hydroxytetrahydrofuran (JPS CHIMIE, Bevaix, Switzerland) in a small amount of toluene is then added dropwise and, after the mixture has been stirred at RT for 2 h, the excess phosgene is expelled with argon. After concentration by evaporation in a rotary evaporator under reduced pressure, the crude title compound is further processed without being further purified.
