The synthesis of the new heterocycles, 4-amino[1]benzofuro[3,2-g]cinnolines, was accomplished by the intramolecular cyclization of the Z-configuration of cyanoarylhydrazones. The latter compounds were obtained via interaction between the diazonium salt of 3-amino-dibenzofuran and various active methylene compounds via the Japp-Klingemann reaction. The alkaline treatment of azo intermediates 4, which
通过氰基芳基azo的Z-构型的分子内环化作用,完成了新的4-氨基[1]苯并呋喃[3,2- g ]喹啉杂环化合物的合成。后者的化合物是通过Japp-Klingemann反应通过3-氨基-二苯并呋喃的重氮盐与各种活性亚甲基化合物的相互作用而获得的。可以在缩合过程中分离出的偶氮中间体4进行碱处理,得到相应的氰基芳基hydr 5。据报道对构型和可能的异构化进行了研究。
