ester function. The second synthetic pathway starts from 4-bromobenzonitrile, which is converted through Suzuki coupling with 4-carboxyphenylboronic acid into 4′-cyano-[1,1′-biphenyl]-4-carboxylic acid, which in turn leads to the desired compound after ring closure of tetrazole. All of the synthesized compounds have been fully characterized by IR and 1H- and 13C-NMR spectroscopy. Single crystal X-ray structures
摘要 报道了 4'-(2H-四唑-5-基)-[1,1'-联苯]-4-羧酸的两种合成方法,4'-(2H-四唑-5-基)-[1,1'-联苯]-4-羧酸是一种用于制备金属-有机骨架的有价值的有机配体。产生目标化合物的第一个反应序列包括[1,1'-联苯]-4-羧酸的碘化,4'-碘-[1,1'-联苯]-4-羧酸甲酯的形成酸、碘与氰基的亲核取代、四唑的闭环和酯官能团的水解。第二条合成途径从 4-溴苯甲腈开始,通过 Suzuki 与 4-羧基苯基硼酸的偶联转化为 4'-氰基-[1,1'-联苯]-4-羧酸,然后再生成所需的化合物四唑的闭环。所有合成的化合物都已通过 IR 和 1H-和 13C-NMR 光谱进行了充分表征。报告了目标化合物和 4'-碘-[1,1'-联苯]-4-羧酸和 4'-氰基-[1,1'-联苯]-的甲酯的单晶 X 射线结构4-羧酸。目标化合物和中间体对大肠杆菌、金黄色葡萄球菌和白色念珠菌没有抗菌活性。
