Article abstract of DOI:10.1055/s-1986-31807

1,4-Dihydropyridines (1a-h) react with s-triazine in the presence of a base to give 1,4-dihydro-1,6-naphthyridinones (2a-h) in a single step in fair to good yields.The title compounds can also be prepared by reaction of 1,4-dihydropyridines with amidaceta
