2-氟-9,10-亚甲二氧基-6[H]-[1]苯并吡喃并[4,3-b]喹啉的合成与表征

Synthesis and characterization of 2-fluor-9,10-methylenedioxy-6[H]-[1]- benzopyran[4,3-b]quinoline

以 6 氟 色满酮 4为原料 ,与 6 氨基胡椒醛发生Friedl nder缩合反应而得到新的喹啉衍生物 2 氟 9,1 0 亚甲二氧基 6 [H] [1 ]苯并吡喃并 [4 ,3 b]喹啉 ,其结构经IR、1 HNMR。

One new quinoline derivative,2 fluor 9,10 methylenedioxy 6[H] [1] benzopyran[4,3 b]quinoline(3),was synthesized from 6 fluor chromanone 4 by Friedlnder condensation reaction.The structure of 3 was confirmed by IR,UV, 1HNMR ,MS and elemental analysis.
