one-pot procedure for the catalytic preparation of the biologically interesting class of carbazoles. The new procedure is based on the combined catalysis of palladium and norbornene starting from o-substituted iodoarenes and N-sulfonylated or N-acetylated o-bromoanilines. A well-known member of this class, carbazomycin A, has been successfully prepared.
本文提供了一种合成简单的一锅法,用于催化制备生物学上有趣的咔唑类化合物。该新方法是基于钯和降冰片烯从邻取代的碘芳烃和N-磺酰化或N-乙酰化的o-溴代苯胺开始的联合催化。已经成功制备了此类的一个著名成员,卡巴霉素A。
