4-dioxide 1, a new series of quinoxaline derivatives 2-12 was synthetized through chemical modification of the 3-amino group, the 2-cyano group and selective mono-deoxygenation of the 1-oxide or 4-oxide groups. On the other hand, two 2,4-diaminopyrimido[4,5-b]quinoxa-line derivatives 13, 14 were obtained condensing 3-amino-2-quinoxaline carbonitriles with quanidine. Some of the new compounds were studied
从3-氨基-2-喹喔啉腈1,4-二氧化物1开始,通过化学修饰3-氨基,2-氰基和选择性地对1进行脱氧合成了一系列新的喹喔啉衍生物2-12。 -氧化或4-氧化基团。另一方面,获得了2,4-二氨基嘧啶基[4,5- b ]喹喔啉系衍生物13、14,其使3-氨基-2-喹喔啉腈与胍缩合。研究了一些新化合物作为血小板聚集抑制剂和降压药。
