A concise and efficient synthesis of the pheromone components of the cocoa pod borer moth, namely (4E,6Z,10Z)-hexadeca-4,6,10-trien-1-ol and (4E,6E,10Z)-hexadeca-4,6,10-trien-1-ol, starting from commercially available materials, was reported. The overall yield was 30.4% and 27.4%, respectively. The stereoselective formation of (E,Z)- or (E,E)-conjugated double bond relied on Sonogashira coupling with
简洁有效地合成了可可荚bore蛾的信息素成分,即(4 E,6 Z,10 Z)-十六烷基-4,6,10-trien-1-ol和(4 E,6 E,10据报道,Z)-十六烷基-4,6,10-三烯-1-醇从可商购获得的材料开始。总产率分别为30.4%和27.4%。(S,Z)或(E,E)共轭双键的立体选择性形成依赖于Sonogashira与(E)-5-溴戊4烯1-醇(由(E)-5-溴戊烯制备的)偶联。4-烯和烯的立体选择性加氢,而10Z-双键是由Wittig反应由4-羟基丁醛和正己基三苯基溴化formed形成的。
