摘要

The electrochemical behaviour of 3-cyano-5-methoxycarbonyl-2, 6-dimethyl-4 (o- nitrophenyl)-1, 4-dihydropyridine and the corresponding N-methyl derivative have been investigated in hydroalcoolic medium. The 4 electron reduction leads to an amino- benzonaphtyridine N-oxide (cyclization from the reaction of the hydroxylamino group with the cyano substituent) when performed in acidic medium; in basic medium, the same ...
