概要

• 論文の詳細を見る

• Irradiation of a mixture of pyridazine N-oxide (I) and primary amine dissolved in dichloromethane resulted in the formation of the corresponding N-substituted pyrrole. Thus, from pyridazine 1-oxide (IA), N-substituted pyrroles (VIIAa-d) were obtained. From 6-methylpyridazine 1-oxide (IB), N-substituted 2-methylpyrroles (VIIBa-d) were obtained. From 3-methylpyridazine 1-oxide (IC), 2-methylpyrroles (VIIB) and their isomers, 3-methylpyrroles (VIIIC) were obtained.
