应用聚合物Wittig试剂合成欧洲玉米螟性信息素

Synthesis of Insect Sex Pheromone of Ostrinia Nubilis using Polymeric Reagent

在溶液中进行Wittig反应,产生的三苯氧膦副产物往往较难从烯烃产物中分离出去,而应用聚合物Wittig试剂,三苯氧膦即留在高分子上,通过过滤就可分离出产物,而聚合物试剂经过还原仍可重复使用.

Polymer-supported Wittig reagent(polystyryldiphenylω-hydroxyl■phosphonium bromide)was used in forming polymeric phosphoranes,which■with propanal in THF to give 11-tetradecen-1-o1 in 84%yield.The pro■tetradecen-1-o1 acetate,was shown by gas chromatagraphy to be a mixture■isomers in 93:7 ratio.
