Described herein is a Cu-catalyzed transformation of peptidic thiol esters and boronic acids into peptidyl ketones that takes place at room temperature in DMF or in DMF/H2O open to air and uses only catalytic quantities of a Cu carboxylate to mediate the reaction. This aerobic transformation occurs only at a thiol ester capable of coordinating to Cu through its S-appendage and is hampered neither by racemization of the reactants or products, nor by the presence of disulfides or of unprotected phenols, alcohols, or indoles.
