Термическая гетероциклизация О-виниловых эфиров акцепторно замещенного ацетамидоксима. Новый путь к 2-аминопирролам

The Thermal Heterocyclysation of l-(pyrrolidin-l-ylcarbonyl)acetamidoxime O-Vinyl Ethers was investigated. 2-Aminopyrroles were shown to be the products of the reaction on the contrary to the cases previously described when other amidoximes gave rise to imidasoles.
