2-Azabicycloheptane-3,4-diones (4): thermal rearrangement of 3-ethoxy-2-azabicyclohept-2-en-4-ones leading to 2-ethoxy-3,4-dihydropyridines

Thermolysis of 3-ethoxy-2-azabicyclohept-2-en-4-ones yielded 2-ethoxy-3,4-dihydropyridines, which is explained by sigmatropic rearrangement followed by cheletropic elimination of CO
