4-Chloro-2-methylfuro[2,3-c]quinoline (IV) was synthesized from ethyl 3-(2-nitrophenyl)-5-methyl-2-furoate and IV was allowed to react with some nucleophiles to afford the corresponding 4-substituted 2-methylfuro-[2,3-c]quinoline derivatives, respectively. On treatment of IV with potassium azide in dimethylsulfoxide, 2-methylfuro[2,3-c]tetrazolo[1,5-a]quinoline was formed path azido-tetrazolo isomerization
由3-(2-硝基苯基)-5-甲基-2-糠酸乙酯合成4-氯-2-甲基呋喃[2,3- c ]喹啉(IV),使IV与某些亲核试剂反应,得到相应的4-取代的2-甲基呋喃-[2,3- c ]喹啉衍生物。在叠氮化钾中在二甲亚砜中进行IV处理后,通过叠氮基-四唑基异构化反应形成了2-甲基呋喃[2,3- c ]四唑[1,5- a ]喹啉。通过还原IV制备2-甲基呋喃-[[2,3- c ]喹啉]。
