total synthesis of Clausenamine-A (3) was developed involving the Suzuki cross-coupling and oxidative coupling reaction. The synthesis of its demethoxylated analogs 1 and 2 were also reported. Resolution of (+)-1, (+)-2, (+)-3 and (−)-1, (−)-2, (−)-3 were performed via their corresponding camphorsulfonates of the racemates. The absolute configurations of (+)-1, (+)-2, (+)-3 and (−)-1, (−)-2, (−)-3 were
涉及铃木交叉偶联和氧化偶联反应的克劳森胺-A(3)的第一个全合成方法得到了发展。还报道了其脱甲氧基化类似物1和2的合成。经由它们的外消旋体的樟脑磺酸盐进行(+)- 1,(+)- 2,(+)- 3和(-)- 1,(-)- 2,(-)- 3的拆分。将(+)- 1,(+)- 2,(+)- 3和(-)- 1,(-)- 2,(-)- 3的绝对构型指定为(a R)和(a S)分别通过X射线分析及其CD光谱分析。简要描述了这些双咔唑对恶性疟原虫的主要细胞毒性活性。
