bromo-substituted 1,6-methano[10]annulenes with sodium thiolates in DMF provides easy access to alkylthio- and arylthio-substituted 1,6-methano[10]annulenes (Schemes 2-4). These compounds are then brominated with N-bromosuccinimide (NBS) to study their reactivity in electrophilic substitution reactions (Schemes 5 and 6). The resulting brominated thio-1,6-methano[10]annulenes are, in a subsequent reaction
在DMF中用硫代硫酸钠处理溴取代的1,6-甲基[10]环戊烯可轻松获得烷硫基和芳硫基取代的1,6-甲基[10]环烯(方案2-4)。然后将这些化合物用N-溴琥珀酰亚胺(NBS)溴化,以研究它们在亲电取代反应中的反应性(方案5和6)。在随后的反应中,将所得的溴化的硫代1,6-甲基[10]环戊烯与(4-硝基苯基)乙炔(13)进行Heck偶联,以合理的收率生产烷基化衍生物14(方案7)。
