The total synthesis of a potent antiplasmodial natural bichalcone, rhuschalcone VI, is described starting from simple and available resorcinol and 4-hydroxybenzaldehyde. Key steps include the solvent-free Aldol syntheses of chalcones, and the successful application of the Suzuki–Miyaura coupling reaction in the synthesis of bichalcones. The present work constitutes a general method for the rapid syntheses
从简单易得的间苯二酚和4-羟基苯甲醛开始,描述了一种有效的抗疟原虫天然联苯并噻唑酮(Ruschalcone VI)的总合成。关键步骤包括查耳酮的无溶剂Aldol合成,以及Suzuki-Miyaura偶联反应在二苯并con的合成中的成功应用。本工作构成了快速合成与杜鹃花酮VI有关的许多比沙可酮的通用方法。一些比沙可康对初生Bodo caudatus表现出中等的抗原生动物活性,这是抗锥虫活性的初步筛选系统,其中大多数几乎没有或没有细胞毒性。
