very efficient methodology for the synthesis of the antibiotics carbazomycin A (1) and B (2) by oxidative coupling of cyclohexa-1,3-diene and the corresponding arylamine 10 (Scheme 5 and Schemes 7 and 9, resp.). The overall process is achieved by a consecutive Fe-induced formation of the CC and the CN bond. The major benefit of our Fe-mediated carbazole synthesis is that the coupling process is possible
我们开发了一种非常有效的方法,用于通过环己-1,3-二烯与相应的芳基胺10的氧化偶合来合成抗生素卡巴霉素A(1)和B(2)(方案5和方案7和9,分别)。 。整个过程是通过连续的铁诱导的CC和CN键形成而实现的。我们的铁介导的咔唑合成的主要好处是,偶联过程可以与完全官能化的芳胺10发生。因此,咔唑生物碱的高度收敛合成是可行的,并且避免了使用经典方法所需的线性多步序列。总合成11和2强调了咔唑骨架的铁介导结构的这一特征。
