A palladium-catalyzed ortho-acylation of N-benzyltriflamides with aldehydes via direct sp2 CH bond activation is described. Benzylamines with a triflamide directing group in the presence of palladium acetate, acetic acid, and tert-butyl hydroperoxide as an oxidant can be effectively coupled with aryl and alkyl aldehydes to provide ortho-acyl-N-benzyltriflamides with a high regioselectivity.
描述了通过直接的sp 2 CH键活化,钯催化的N-苄基三氟化物与醛的邻位酰化。在乙酸钯,乙酸和叔丁基氢过氧化物的存在下,具有三氟化物导向基团的苄胺可以有效地与芳基和烷基醛偶联,以提供具有高区域选择性的邻酰基-N-苄基三氟化物。
