摘 要:1,6-亚甲基桥[10]轮烯-4-溴-3-羧酸乙酯经LiAlH4还原后再在冰水浴下与PBr3反应制得3-溴甲基-4-溴-1,6-亚甲基桥[10]轮烯(3);3与PPh3在苯中回流,然后与对甲氧基苯甲醛进行Wittig反应,再经分子内异构化制得3-(p-甲氧基苯乙烯基)-4-溴-1,6-亚甲基桥[10]轮烯(trans-5);trans-5在钯盐催化下完成分子间耦合合成了基于1,6-亚甲基桥[10]轮烯的多环化合物,其结构经NMR,IR和MS表征。3-Bromomethyl-4-bromo-1,6-methano[10] annulene(3) was prepared by the reduction of ethyl 1,6-methano[10] annulene-4-bromo-3-carboxylate with LiAlH4,then reacted with PBr3 under icewater bath.3-(p-methoxystyryl)-4-bromo-1,6-methanoannulene(trans-5) was prepared by the reaction of 3 with PPh3 in benzene,Wittig reaction with p-methoxybenzaldehyde,and then isomerization of intramolecular.Polycyclic compound based on 1,6-methano[10] annulene was synthesized by intermolecular coupling reaction of trans-5 using palladium as the catalyst.The structures were confirmed by NMR,IR and MS.
