Article abstract of DOI:10.1248/cpb.33.3540

Irradiation of pyridazin-3-one l-ethoxycarbonylimide (9a) resulted in ring contraction to give the azamaleimide (11), whereas the 6-methyl derivative (9b), upon irradiation, afforded the 3-pyrrolin-2-one (12). On the other hand, the photolysis of 2-methyl
