C-H functionalization of aliphatic carboxylic acids without attaching exogenous auxiliary has been so far limited at the proximal β-position. In this work, we demonstrate a ligand enabled palladium catalyzed first regioselective distal γ-C(sp3)-H f

Directed C-H functionalization has been realized as a complementary tool to the traditional approaches for a straightforward access of non-proteinogenic amino acids; albeit such a process is restricted mostly up to the γ-position. In the present wor

Ready availability, low cost and low toxicity of cobalt salts have redirected the attention of researchers away from noble metals, such as Pd, Rh, and Ir, towards Co in the field of C–H functionalization. In this context, the examples of Co-catalys

Achieving site-selective C-H functionalization of arene is a fundamental challenge, as it is mainly controlled by the electronic nature of the molecules. A chelation-assisted C-H functionalization strategy overcomes the selectivity issues by utilizin
