摘要
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Suzuki-Miyaura反应合成了2-硝基-4’-甲氧基联苯,然后经亚磷酸三乙酯还原反应,三溴化硼催化脱甲基化合成了目标产物2-羟基咔唑,总收率68.9%.通过1 HNMR、13 C NMR表征了合成化合物结构.
2-nitro-4'-methoxy-biphenyl was synthesized with 2-bromonitrobenzene as the starting material,sequentially reacting with bis(pinacolato)diboron and 4-bromoanisole via Suzuki-Miyaura reaction.Then this compound was reduced with triethylphosphite,followed by demethylation with BBr3 to synthesize the target product 2-hydroxycarbazole with the total yield of 68.9%.Synthetic compound was characterized by ^1 HNMR and ^13 C NMR.
