The synthesis of C-ring quinoxaline-substituted sinomenine 1,2,3-triazole derivatives at the 4-OH via click reactions is accomplished, and a total of 16 novel sinomenine double N-heterocyclic derivatives are obtained in 74%–95% yields. The C-ring is first transformed into a 1,2-diketone structure under the action of hydrochloric acid, and then reacted with o-phenylenediamine to obtain a C-ring qui
通过点击反应在4-OH上合成了C环喹喔啉取代的青藤碱1,2,3-三唑衍生物,共获得16种新型青藤碱双N-杂环衍生物,产率74%~95% . C环在盐酸作用下先转变为1,2-二酮结构,再与邻苯二胺反应得到C环喹喔啉取代结构。青藤碱的4-OH与氯丙炔反应生成炔基青藤碱,然后与叠氮化钠和各种苄基氯反应生成目标化合物。所有合成的衍生物均通过傅里叶变换红外光谱、高分辨率质谱、1H NMR 和 13C NMR 光谱进行表征。
