The synthesis of pyridine derivatives is reported starting from the new dienamino esters 2. Thermal cyclization of 2 afforded the ethyl 2-amino-3-pyridinecarboxylate derivatives 3; from the reaction of 2 in sodium ethoxide the 2-aminopyridines 3 and 4, and the 1,2-dihydro-2-oxopyridines 5 and 6 were obtained.

Abstract
The synthesis of pyridine derivatives is reported starting from the new dienamino esters 2. Thermal cyclization of 2 afforded the ethyl 2-amino-3-pyridinecarboxylate derivatives 3; from the reaction of 2 in sodium ethoxide the 2-aminopyridines 3 and 4, and the 1,2-dihydro-2-oxopyridines 5 and 6 were obtained.
