alkylation occurred primarily on N-5 (1:0.8:0.8) or N-6 (1:1.5:1.5) leading to the isolation of 14a or 14b as a major product. Accordingly, major product 15a (2/(MeO)2SO2/K2CO3=1:2:2) or 15b (1:1:1), respectively, was obtained by alkylation of 12 while 16a (13/(MeO)2SO2/K2CO3=1:2:2) or 16b (1:1:1), respectively, was obtained by alkylation of 13. The in vitro anticancer assay indicated 5-methylated derivatives
本报告介绍了某些11-取代的6H-吲哚并[2,3-b]喹啉及其甲基化衍生物的合成和抗癌作用。这些6H-吲哚并[2,3-b]喹啉衍生物11-13由可商购的1,4-二羟基喹啉通过烷基化,氯化,亲核反应和环环化制备。取决于11,(MeO)2SO2和K2CO3的比例,烷基化主要发生在N-5(1:0.8:0.8)或N-6(1:1.5:1.5)上,导致分离出14a或14b作为主要产品。因此,通过将12进行烷基化而将16a(13 /(MeO)2SO2 / K2CO3)烷基化分别获得主要产物15a(2 /(MeO)2SO2 / K2CO3 = 1:2:2)或15b(1:1:1)。 = 1:2:2)或16b(1:1:1)分别通过13的烷基化获得。体外抗癌实验表明,5-甲基化衍生物14a,15a,
