A procedure is described for the stepwise introduction of substituents (hydrogen included) into the imidazole ring by FGI of the bromine atoms in 1-protected 2,4,5-tribromoimidazoles in the order 2 → 5 → 4 using halogen-metal exchange techniques.
描述了一种通过卤素-金属交换技术,通过FGI将2-被保护的2,4,5-三溴咪唑中的溴原子按2→5→4的顺序逐步引入取代基(包括氢)到咪唑环中的方法。
