Abstract

The ability to incorporate non-canonical amino acids into proteins by genetic or chemical methods allows one to introduce novel chemical properties into a protein at a defined residue. Such a residue may then be modified using common organic transformations. In this way, the structure or function of the peptide may be altered without perturbing any of the other neighbouring amino acids in the peptide chain. Here, we describe the syntheses and potential applications of multiple para-substituted phenylalanine derivatives comprising an isothiocyanate, α-diazoketone, or nitrone functionality. In all, three novel amino acids were synthesized in good overall yields. These non-canonical amino acids permit the further development of in vitro and in vivo chemoselective and regioselective bioconjugate reactions not possible with other reagents.
