(NHC)-catalyzed benzylic C–H acylation with aldehydes via the hydrogen atom transfer strategy is disclosed. This transformation involves a sequence of single-electron transfer, 1,5-hydrogen atom transfer, and radical cross-coupling steps. This method offers facile access to various highly functionalized ketones and exhibits good chemical yields and functional group tolerance.
公开了一种通过氢原子转移策略与醛类进行N-氟代羧酰胺定向的 N-杂环卡宾 (NHC) 催化的苄基 C-H 酰化的方法。这种转变涉及一系列单电子转移、1,5-氢原子转移和自由基交叉偶联步骤。该方法提供了对各种高度官能化酮的轻松访问,并表现出良好的化学产率和官能团耐受性。
