Etheneamine 1 and its methyl derivatives 2-7 have been synthesized from the adducts 8-14 by a retro-Diels-Alder reaction under flash thermolytic conditions.The primary enamines 1-4 have been identified (IR, (1)H and (13)C NMR in a pure state at -80 deg C; at the same temperature, the enamines 5-7, less stable, are already accompanied by their tautomeric imines 33 or 34.When warmed up to room temperature, the enamines 1-7 lead, following to their substitution, either to nitrogen heterocycles (30, 42) or to acyclic azadienes (35-37, 39, 40).
