摘要
Reactions of succinyl chloride with 4-hydroxy-3-methoxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyde gave the corresponding succinates which were brought into the condensation with naphthalen-2-amine to obtain Schiff bases. The latter reacted with CH acids (cyclohexane-1,3-dione and 5,5-dimethylcyclohexane-1,3-dione) to form bis[2-alkoxy-4-(11-oxo-7,8,9,10,11,12-hexahydrobenzo[a]acridin-12-yl)phenyl]-succinates which can also be obtained by three-component heterocyclization of naphthalen-2-amine with bis-(2-alkoxy-4-formylphenyl)succinates and CH acid.
