Abstract: Photolysis of model peptides containing alpha-carboxy-2-nitrobenzyl (CNB) or alpha-carboxy-4,5-dimethoxy-2-nitrobenzyl (CDMNB) protected cysteines in aqueous solution gives the expected 2-nitrobenzyl-type photocleavage and can be accompanied by photodecarboxylation depending on structural aspects.
