Electrochemical reduction of 5-oxoindeno[1,2-b]pyridinium perchlorates in the presence of alkylating agents

It was established that 9b-substituted 5,9b-dihydroindenopyridines are formed in addition to the reduction products on preparative electrochemical reduction of 5-oxoindeno[1,2-b]pyridinium perchlorates at a mercury electrode in acetonitrile in the presence of alkylating agents.

C- AND N-ALKYLATION OF 4,5-DIHYDRO-1H-INDENOPYRIDINE DERIVATIVES

2-Methyl-4-aryl-5-oxo-4,5-dihydro-1H-indenopyridine derivatives react with methyl iodide in an aprotic medium in the presence of alkaline agents to give C- and N-alkylation products, viz., 2,4a-dimethyl- and 1,2-dimethyl-4-aryl-5-oxo-4,5-dihydroind
