DOI: 10.1039/b9nj00474b
Flash vacuum pyrolysis (FVP) of the aminopyridazinone derivatives of Meldrums acid at 600 °C (0.02 Torr) results in generation of an imidoylketene intermediate followed by cyclisation. The 4-amino compounds shown lead to mixtures of pyrido[2,3-d]pyridazines and pyrrolo[3,2-c]pyridazines. A suggested mechanism for the formation of the latter is supported by DFT calculations.
