A UVA-light-mediated synthesis of amides from carboxylic acids and amines or amino acids is presented, taking advantage of a novel photoactivation mode using pyridine-CBr4. Mechanistic studies by DI-HRMS provide experimental evidence for the formation of various intermediates. Application in the synthesis of industrially interesting or bioactive compounds was demonstrated.
