尽管在C-H键官能化反应中广泛使用氨基甲酸酯作为导向基团,但该导向基团的还原去除并不简单。目前可用的方法仅限于使用IniPrMgX或氢化硅烷作为还原剂的镍催化反应,留下官能团相容性问题有待解决。在此,我们报告了铑催化的还原裂解芳基氨基甲酸酯usingPrOH作为一个温和的还原剂。
Despite the widespread use of carbamates as a directing group in C–H bond-functionalization reactions, reductive removal of this directing group is not straightforward. Currently available methods are limited to nickel-catalyzed reactions usingiPrMgX or hydrosilane as a reductant, leaving the functional group compatibility issue to be solved. Herein, we report rhodium-catalyzed reductive cleavage of aryl carbamates usingiPrOH as a milder reductant.
