The Chemistry of 6-Dialkylamino-2H-1,3-oxazin-2-ones. Reversible Thermal Ring-opening and Cycloaddition Reactions with N-Arylmaleimides and 1-Diethylaminopropyne. X-Ray Crystal Structures of a 5H-2-Pyridone and a 1H-2-Pyridone

Flash-vacuum pyrolysis of the 1,3-oxazin-2-ones (1) and (9) gave the valence-isomeric carbamoylvinyl isocyanates (8) and (10), respectively, which recyclised to the oxazinones at room temperature.The oxazinones reacted with N-arylmaleimides in a Diels-Alder fashion; with 1-diethylaminopropyne, however, the first oxazinone yielded the isomeric pyridones (17) and (21), whose structures were determined by X-ray analysis.
