series of six dihydropyridine-fused coumarins were synthesized and electrochemically characterized in dimethylformamide (DMF). Dihydropyridine ring oxidation on glassycarbon electrode (GCE) for condensed heterocyclic compounds revealed a single anodic peak. Oxidation potential values correlated fairly well with substituent effects at 9-position. The overall oxidation mechanism involved 2-electrons and

pyridine-fused coumarins were synthesised and electrochemically characterised in aprotic medium. In both series, the most easily reducible groups were the endocyclic carbonyl groups. The electrochemical mechanism for both types of compounds is strongly dependent on the experimental time-scale. Cyclic voltammetric (CV) reduction on a glassy carbonelectrode (GCE) of the endocyclic carbonyl group of d
