Several 4H-pyrano[3,2-h]quinoline (3a–d, 4a, 7a,b, 9a–c, 10a,b, 11a,b, and 13a–c) and 7H-pyrimido[4′,5′:6,5]pyrano[3,2-h]quinoline derivatives (8a–c) were obtained by treatment of 8-hydroxyquinoline (1a) and 8-hydroxy-2-methylquinoline (1b) with α-cyano-p-chloro/bromocinnamonitrile (2a,b) or 4H-pyrano[3,2-h]quinoline derivatives (3a,c,d) with different electrophilic reagents followed by nucleophilic
几个4 H-吡喃并[3,2- h ]喹啉(3a - d,4a,7a,b,9a - c,10a,b,11a,b和13a - c)和7 H-嘧啶[4',通过用α-氰基-p处理8-羟基喹啉(1a)和8-羟基-2-甲基喹啉(1b)获得5':6,5]吡喃并[3,2- h ]喹啉衍生物(8a – c)。-氯/溴代肉桂腈(2a,b)或4 H-吡喃并[3,2- h ]喹啉衍生物(3a,c,d),先用不同的亲电试剂,再用亲核试剂。这些化合物的结构是根据光谱数据确定的。与长春花碱相比,研究了合成化合物的抗肿瘤活性。其中,化合物3c,d,4a,8b,9b,c,11a,b和13a,c与长春碱相比,抑制癌细胞的生长。讨论了构效关系。
