Direct amidation of the phenylalanine moiety in short peptides via Pd-catalyzed C–H activation/C–N formation†
Abstract
Selective modifications of life's basic components, such as polypeptides, are of great importance in both chemistry and biology. Herein, we have developed an unprecedented intramolecular amidation of the phenylalanine moiety in dipeptides via Pd-catalyzed sp2 C–H activation and C–N formation.
