The title compound, active component of the sex pheromone of Aonidiella aurantii (California Red Scale), was synthesized in three steps starting from S-citronellyl acetate with a 30% overall yield. The key feature of the synthesis is a copper salt assisted, highly regioselective attack of the 4-butenyl bromide Grignard reagent on the γ-site of the chloroallylic system of (S)-8-chloro-3,7-dimethyl-6-octenyl acetate (8a).
标题化合物,即加州红锈粉虱(Aonidiella aurantii)性信息素的活性成分,经过三步合成,自S-柠檬烯醇乙酸酯起始,总体产率为30%。合成的关键特征是铜盐辅助下,4-丁烯基溴化格氏试剂对(S)-8-氯-3,7-二甲基-6-辛烯基乙酸酯(8a)的氯烯基体系γ位的高度区域选择性攻击。
