为得到3,4-二取代双环硫化磷酸酯的中间体5-叔丁基-5-(1'-羟基-2'-甲基丙基)-2,2-二甲基-1,3-二氧六环, 通过5-叔丁基-5-甲酰基-2,2-二甲基-1,3-二氧六环与异丙基溴化镁反应没有得到目标化合物, 而得到了还原产物, 改用异丙基锂代替异丙基溴化镁反应后得到目标化合物, 通过超声波辅助反应, 大幅度提高了反应收率.

关键词: 异丙基锂, 异丙基溴化镁, 超声波辐射, 3,4-二取代双环硫化磷酸酯

In order to get the intermediate of 3,4-disubstituted bicyclophosphorothionate of 5-tert-butyl-5-(1-hydroxy-2-methylpropyl)-2,2-dimethyl-1,3-dioxane, a method of reacting isopropyl magnesium bromide with 5-tert-butyl-5-formyl-2,2-dimethyl-1,3-dioxane was attempted but failed, since reduction product of the formyl was obtained. The desired compound was achieved by using isopropyl lithium instead of isopropyl magnesium bromide. The yield can be much improved by using an ultrasonic method during the preparation of alkyl lithium.

Key words: isopropyl lithium, 3,4-disubstituted bicyclophos-phorothionate, ultrasonic irradiation, isopropyl magnesium bromide
