Synthesis of new heterotricyclic compounds containing the [1,8]naphthyridine group by thermal isomerization of 2-dialkylamino-3-vinylpyridines

2-N,N-Dialkylamino-3-(2,2-dicyanovinyl)pyridines react thermally in polar solvents via [1,5] hydrogen transfer followed by carbon-carbon bond formation to yield heterotricyclic compounds containing the [1,8]naphthyridine group. The reaction time is marked
