A facile synthesis of indolo[3,2,1-jk]carbazoles via palladium-catalyzed intramolecular cyclization
A new efficient synthesis of indolo[3,2,1-jk]carbazoles by the palladium-catalyzed cyclization of N-(2-bromoaryl)carbazoles is described. The reaction involves intramolecular C–C bond formation, coupled with the cleavage of a C–X bond and a C–H bond on carbazole ring. Substitutions on N-aryl core with either electron-donating or electron-withdrawing groups are introduced, and different reaction factors
描述了一种新的高效合成吲哚[3,2,1- jk ]咔唑的方法,该方法通过钯催化的N-(2-溴芳基)咔唑的环化反应来实现。该反应涉及分子内CC键的形成,以及咔唑环上CX键和CH键的断裂。引入具有给电子基团或吸电子基团的N-芳基核上的取代基,并评估了用于环化的不同反应因子。
