reported. In the presence of quinidine catalyst, their reactions with α-unsubstituted β-naphthols proceeded through the N-center to furnish α-imino-β-naphthalenones in high yields. Upon exposure to α-substituted β-naphthols in the presence of copper catalyst, an alteration of regioselectivity was observed to produce α-aminoxylation products. The reaction is scalable, tolerates a wide spectrum of functional
据报道,亚硝基羰基在β-萘酚的氧化脱芳香化中具有不同的反应性。在奎尼丁催化剂的存在下,它们与α-未取代的β-萘酚的反应通过N-中心进行,以高产率提供α-亚氨基-β-萘烯酮。在铜催化剂存在下暴露于α-取代的β-萘酚后,观察到区域选择性的变化产生α-氨基木糖基化产物。该反应是可扩展的,可耐受各种官能团,并且代表了α-未取代的β-萘酚脱芳香化的罕见例子。
