本文以邻溴硝基苯为起始原料,依次与双(频那醇)合二硼,对溴苯甲醚经Miyaura-Suzuki“一锅两步”反应合成2-硝基-4’-甲氧基联苯,然后经亚磷酸三乙酯还原,BBr3催化脱甲基合成了目标产物2-羟基咔唑。1HNMR,13C NMR表征了目标化合物结构。

In this paper, two-step one-pot synthesis of 2-nitro-4'-methoxy-biphenyl was carried out with 2-bromonitrobenzene as the starting material, by Suzuki-Miyaura cross-coupling reaction sequentially with bis (pinacolato) diboron and 4-bromoanisole. The product was then reduced with triethyl phosphite, followed by demethylation catalyzed by BBr3 to synthesize the target product 2-hydroxy carbazole, which was characterized by 1HNMR and 13C NMR.
