An effective and operationally simple protocol is reported for the synthesis of versatile carbazoles. With water as a co-solvent, visible-light rather than various metals is used to facilitate the conversion of readily available 2-azidobiphenyls under mild conditions. Various functionalized bioactive natural alkaloids, such as glycoborine, clausine C, clausine L, clausine H and clauszoline K, were
据报道,一种有效且操作简单的方案可用于合成多种咔唑。以水为助溶剂,在温和的条件下,使用可见光而不是各种金属来促进易于获得的2-叠氮联苯的转化。以氮作为唯一副产物有效地合成了各种功能化的生物活性天然生物碱,如糖硼烷,克劳斯碱C,克劳斯碱L,克劳斯碱H和克唑索林K。该反应可以在水,酸性或碱性缓冲溶液中进行,显示出其在生物化学中的应用潜力。
