This study was focused on N-difluoromethylation of monosubstituted polydentate azoles (imidazoles, pyrazoles, and 1,2,4-triazoles) having two or three reactive sites. The substituent effects and role of reaction conditions in determining the product ratio was explored. In the majority of cases, the obtained mixtures of isomers were separated. The target products containing halogen substituents, amino
这项研究集中在具有两个或三个反应位点的单取代多齿唑(咪唑,吡唑和1,2,4-三唑)的N-二氟甲基化上。探索了取代基效应和反应条件在确定产物比率中的作用。在大多数情况下,分离得到的异构体混合物。环中含有卤素取代基,氨基或羧基的目标产物可作为合成实际有用产物的有价值的起始化合物。
