Tandem transformations of 10-substituted tetrahydrobenzo[b][1,6] naphthyridines resulted from the Michael addition of the nitrogen atom of the tetrahydropyridine fragment to the triple bond of activated alkynes

A reaction of 10-R-substituted tetrahydrobenzo[b][1,6]naphthyridines (R = CN, CONH2, Me) with dimethyl acetylenedicarboxylate, methyl and ethyl propiolates, and acetylacetylene has been studied. It was found that 1-acryloyl-10-cyanotetrahydrobe
