A simple synthesis of beta-acaridial [(E)-1], the active principle of the sex, alarm and aggregation pheromone among astigmatid mites, was achieved in 5 steps from 1,2,4-butanetriol 2 in a 19% overall yield. Its analog, beta-acariolal 8, was also prepared in a 63% yield by oxidation of the intermediate, beta-acaridiol [(E)-7], with pyridinium dichromate (PDC). This synthetic route also gave beta-(Z)-acaridiol
从1,2,4-丁三醇2分5步就可以轻松合成β-芳烃[(E)-1],这是散光螨中性,警报和聚集信息素的有效成分,总产率为19% 。还通过用重铬酸吡啶鎓(PDC)氧化中间体β-ac二醇[[E] -7],以63%的产率制备了其类似物β-ari醛8。通过在Wittig反应中使用Z-选择性碱,该合成途径还得到了β-(Z)-ac二醇[(Z)-7]。将(Z)-7氧化,得到新的单萜β-(Z)-芳烃[(Z)-1],该化合物被作为多叶草的分泌物中的痕量成分与8一起检测到。
