A chemoselective electrooxidative heterocoupling of two different enamines is reported for the synthesis of unsymmetrically substituted NH-pyrroles. A “magic effect” of the additive trifluoroethanol is utilized to achieve the desired chemoselectivity by tuning the oxidation potentials and controlling the activation energy of the rate-determining step.
据报道,两种不同烯胺的化学选择性电氧化杂偶联可用于合成不对称取代的 NH-吡咯。添加剂三氟乙醇的“神奇效应”用于通过调节氧化电位和控制速率决定步骤的活化能来实现所需的化学选择性。
