Total syntheses of pyocyanin, lavanducyanin, and marinocyanins A and B have been accomplished. The N-substituted phenazin-1-one skeleton, a common framework of these natural products, was constructed through the oxidative condensation of pyrogallol with N-substituted benzene-1,2-diamine under an oxygen atmosphere in a single step. Regioselective bromination with N-bromosuccinimide at the C-2 position
洋青素,薰衣草花苷和马来花青素A和B的总合成已完成。所述Ñ取代吩嗪-1-酮骨架,这些天然产品的一个共同的框架,通过邻苯三酚与的氧化缩合构造Ñ在单个步骤中-取代的氧气氛下苯-1,2-二胺。在N-烷基化的吩嗪-1-酮的C-2位用N-溴琥珀酰亚胺进行区域选择性溴化,得到溴化的天然产物。
