cross-couplings of nitroarenes and heteroarylboronate esters has been developed. A number of heterobiaryl compounds containing pyridine, pyrimidine, quinoline, furan, thiophene, and pyrazole were prepared using [Pd(cinnamyl)Cl]2/2-aryl-5-(2,4,6-triisopropylphenyl)-2,3-imidazolylidene[1,5-a]pyridines as the catalysts in good to excellent yields. The synthetic practicality of this approach is demonstrated through
已经开发了钯催化的硝基芳烃和杂芳基硼酸酯的 Suzuki-Miyaura 交叉偶联。使用[Pd(肉桂基)Cl] 2 /2-芳基-5-(2,4,6-三异丙基苯基)-2,3-制备了许多含有吡啶、嘧啶、喹啉、呋喃、噻吩和吡唑的杂二芳基化合物咪唑亚基[1,5- a ]吡啶作为催化剂,收率良好。这种方法的合成实用性通过类药物分子的合成得到证明。
