Direct C-H functionalization of aromatic compounds is a powerful tool for organic synthesis; however, differentiation among the ubiquitous and often chemically similar C-H bonds remains a significant challenge. Conflation with coordinating or directing groups incorporated into the intended substrate has helped address these limitations, although access to remote sites remains limited. Herein, we report an operationally simple and sustainable direct meta-selective H2N amination of benzylic and related aromatic picolinates under conditions mild enough to modify polyfunctional and late-stage molecules.
Transesterification for synthesis of carboxylates using aldehydes as acyl donors via C-H and C-O bond activations

A new type of transesterification between aryl, heteroaryl, alkyl N-heteroarene-2-carboxylates and various aldehydes by C-H and C-O bond activations has been developed for the synthesis of versatile carboxylates. A possible mechanism containing oxidative addition of acyl-O bond in parent ester and radical cleavage of sp2 C-H bond in aldehyde is proposed.
