The Cu/ABNO-catalyzed aerobicoxidative coupling of diols and primary amines to access N-substituted pyrroles is highlighted (ABNO = 9-azabicyclo[3.3.1]nonane N-oxyl). The reaction proceeds at roomtemperature with an O2 balloon as the oxidant using commercially available materials as the substrates and catalysts. The catalyst system is characterized by a broad range of substrates and a good tolerance
突出显示了 Cu/ABNO 催化的二醇和伯胺的需氧氧化偶联以获得 N 取代的吡咯(ABNO = 9-氮杂双环 [3.3.1] 壬烷N-氧基)。反应在室温下以 O 2气球作为氧化剂进行,使用市售材料作为底物和催化剂。该催化剂体系的特点是广泛的底物和对敏感官能团的良好耐受性。克级实验证明了该系统的实用性。
