An improved method of preparation of halopropargyl alcohol is described. Hydration of halopropargyl alcohol followed by hydrolysis gave dihydroxyacetone which was identified as its dibenzoate. 2-Butyne-1,4-diol was converted into acetoxymethyl vinyl ketone. 1,4-Diacetoxy-3-bromobutan-2-one obtained by the addition of acetyl hypobromite to the vinyl ketone was treated with silver acetate to yield t
描述了制备卤代炔丙醇的改进方法。卤代炔丙醇水合后水解得到二羟基丙酮,经鉴定为二苯甲酸酯。2-丁炔-1,4-二醇转化为乙酰氧基甲基乙烯基酮。1,4-Diacetoxy-3-bromobutan-2-one 通过将乙酰次溴酸盐添加到乙烯基酮中而获得,用乙酸银处理以产生三-O-乙酰基-DL-赤藓酮糖。三乙酸酯的水解提供DL-赤藓酮糖,其被鉴定为苯腙。
