实验步骤: 7.13 g (0.04 mol) of 4-benzyloxy-2-buten-1-ol was dissolved in 250 ml of dichloromethane and 8.6 g (0.04 mol) of m-chloroperbenzoic acid (purity: 80%) was added thereto in four portions under ice-cooling and stirring. After stirring the mixture at the same temperature for additional 1 hour, the precipitate thus formed was filtered off. The filtrate was poured into a 10% aqueous solution of sodium hydrosulfite, extracted with dichloromethane, washed with water, and dried. After distilling off the solvent, the obtained liquid residue was purified by column chromatography (silica gel, hexane/ether) to thereby give 7.7 g of 4-benzyloxy-2,3-epoxybutan-1-ol as a colorless liquid. in four portions under ice-cooling After stirring the mixture at the same temperature for additional 1 hour the precipitate thus formed was filtered off The filtrate was poured into a 10% aqueous solution of sodium hydrosulfite extracted with dichloromethane washed with water dried After distilling off the solvent the obtained liquid residue was purified by column chromatography (silica gel, hexane/ether)
