A variety of functionalized N-alkylated carbazolones were prepared via N-alkylation of 3-(arylamino)cyclohex-2-enones followed by an intramolecular oxidative coupling mediated by Pd(OAc)2 under an oxygen atmosphere. This approach adopts an inverted sequence, consisting of the conventional annulation and subsequent N-alkylation.
通过N-烷基化3-(芳胺基)环己-2-烯酮,然后在
氧气氛围下经Pd(OAc)2介导的分子内氧化偶联反应,制备了一系列功能化的N-烷基化
咔唑酮。该方法采用逆序策略,包含传统的环化反应和随后的N-烷基化步骤。
