The flexible and efficient synthesis of two structurally similar carbazole derivatives is described. This general strategy features an intramolecular palladium-mediated biaryl coupling reaction to join two aromatic domains of the target molecules. Formation of the carbazole core is accomplished via nitrene insertion. The synthesis of secretory phospholipase A2 (sPLA2) inhibitors LSN433771 (1) and LSN426891
描述了两种结构相似的咔唑衍生物的灵活而有效的合成。该一般策略以分子内钯介导的联芳基偶联反应为特征,以连接靶分子的两个芳族结构域。咔唑核的形成是通过氮的插入来完成的。详细介绍了分泌型磷脂酶A 2(sPLA 2)抑制剂LSN433771(1)和LSN426891(2)的合成。
