Synthèse de γ-lactames et de perhydro-1,2-pyridazin-3-ones polyfonctionnels.
摘要:
Direct condensation, in methanol, of primary amines on 2-(1-carbethoxy-1-hydroxyethyl)acrylonitrile yielded to alpha and beta-functionalized gamma-lactames 6(a-f). The same reaction with hydrazines gave perhydro-1,2-pyridazin-3-ones 7 and 8 when nitrogen is not dialkylated.
