title: Convenient and efficient preparations of azodye-labeled peptides.
abstract: N-(4-Arylazobenzoyl)-1H-benzotriazoles 15a, 15b react with dipeptides 12a-d, (12d+12d') and tripeptides 14a, 14b to give azodye labeled-dipeptides (16a-e), (16d+16d'), (16e+16e') and -tripeptides 16f, 16g in high yields (73-93%) with retention of chirality.
