benzo[b]furans from 2-bromo- and 2-chloro-6-iodo-4-substituted phenols through a consecutive copper- and/or palladium-catalyzed assembly and functionalization process is described. Functionalization at the C(7) position is carried out by Suzuki–Miyaura cross-coupling, alkynylation, alkenylation, and C–N bond forming reactions. A one-pot protocol for the synthesis of 2,5,7-trisubstituted benzo[b]furans
完整的细节以及对范围,局限性的研究,以及进一步阐述从2-溴-和2-氯-6-碘-合成2,5,7-三取代的苯并[ b ]呋喃的简单方法。描述了通过连续的铜和/或钯催化的组装和官能化过程的4-取代的苯酚。C(7)位置的功能化是通过Suzuki-Miyaura交叉偶联,炔基化,烯基化和C–N键形成反应进行的。还报道了一锅法合成2,5,7-三取代的苯并[ b ]呋喃。
