WebWith the Buchwald group, we developed a new approach to the arylation of selenocysteine in unprotected peptides: instead of relying on the nucleophilic character of Sec, we arylated oxidized Sec electrophiles using boronic acid reagents via a copper-mediated process. The reaction is chemoselective, enabling Sec arylation in a complex peptide.
