A protocol for a tandem Pd/Cu-catalyzed intermolecular cross-coupling cascade between o-bromobenzoic acids and 2-(2-bromoaryl)-1H-benzo[d]imidazoles or the corresponding imidazoles is presented. The protocol provides conceptually novel and controlled access to synthetically useful N-fused (benzo)imidazophenanthridine scaffolds with high efficiency, a broad substrate scope, and excellent functional
介绍了邻溴苯甲酸和 2-(2-溴芳基)-1 H-苯并 [ d ] 咪唑或相应咪唑之间串联 Pd/Cu 催化分子间交叉偶联级联的方案。该协议提供了概念上新颖且可控的途径,可用于合成有用的N-融合(苯并)咪唑并菲啶支架,具有高效率、广泛的底物范围和出色的官能团相容性。
