Vanillin esters of aromatic carboxylic acids in the synthesis of benzo[a]acridine and benzo[b][4,7]phenanthroline derivatives
摘要:
By condensation of vanillin esters of substituted benzoic acids with 2-naphthylamine and 6-quinolylamines and also with cyclic beta-diketones (1,3-cyclohexanedione and dimedone) 2-methoxy-4-(11-oxo-7,8,9,10,11,12-hexahydrobenzo[a]acridin-12-yl)- and 2-methoxy-4-(11-oxo-7,8,9,10,11,12-hexabydrobenzo[b][4,7]-phenanthrolin-12-yl)phenyl benzoates were prepared.
