A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting materials under mild conditions. A highly selective ligand for estrogen receptor β was prepared in three steps by employing this method.
一种新型高效的铜催化分子内胺化反应已被开发出来,可以在温和条件下从易于获得的起始材料直接合成各种多取代2H-吲唘和1H-吡唑衍生物。通过采用这种方法,仅用三步就制备出了一种高选择性的雌激素受体β配体。
