The Masuda borylation/Suzuki arylation (MBSA) sequence starting from N-protected 3-iodoindoles has successfully been extended to the coupling of five-membered heterocycles and indoles in the arylation step, which could not be achieved with previously developed MBSA methods. By this approach the one-pot nature of the method as well as the use of a simple catalyst system has been retained. The applicability
从 N 保护的 3-碘吲哚开始的 Masuda 硼酸化/铃木芳基化 (MBSA) 序列已成功扩展到芳基化步骤中五元杂环和吲哚的偶联,这是以前开发的 MBSA 方法无法实现的。通过这种方法,该方法的一锅法特性以及简单催化剂体系的使用得到了保留。该方法的适用性已通过 camalexins 和 3,3'-联吲哚的轻松合成得到证明,这些化合物由于其显着的抗真菌、抗菌和细胞毒性活性而受到特别关注。
