Abstract
The course of electrochemical and chemical oxidation of quaternized py ridyl dihydropyridines has been compared. The splitting off of the car boxylato group from the betaine structure as the substituent in positi on 4 of 1,4-dihydropyridine ring seems to be the decisive factor in th e intramolecular cycloaddition forming indolizines during oxidation. T he mechanisms of the electrochemical oxidation in acetonitrile of both tetrahydro-and dihydroindolizines have been studied using rrde voltam metry. (C) 1997 Elsevier Science Ltd.
