Synthesis of novel thiazoloindolo[3,2-c]quinoline and 8-substituted-11H-indolo[3,2-c]quinolines was performed via Graebe–Ullmann thermal cyclization from appropriated N-arylated benzotriazoles. 7H-4,7-Diaza-benzo[de]anthracene, a by-product reaction structurally closed to pyridoacridine skeleton was also identified.
新型的噻唑并吲哚并[3,2 - c ]喹啉和8-取代的11 H-吲哚并[3,2- c ]喹啉是通过Graebe-Ullmann热环合反应从合适的N-芳基化苯并三唑中合成的。还鉴定出7 H -4,7-二氮杂苯并[ de ]蒽,其在结构上与吡啶ido啶骨架相近。
