Application
Fmoc-Asp(CSY)-OH is an Fmoc-protected aspartic acid residue developed in the Bode Lab that contains a cyanosulfurylide (CSY) as a carboxylic-acid protecting group that completely suppresses aspartimide formation in peptide synthesis, a long-standing challenge in peptide chemistry that occurs during Fmoc removal or peptide coupling and affects peptide yield and sequences. Amenable to SPPS, deprotection is achieved under aqueous conditions with electrophilic halogenating agents to convert the ylide to the free acid. Furthermore, the hydrophilic nature of the ylide protecting group improves overall peptide efficiency and solubility.

Although peptide chemistry has made great progress, the frequent occurrence of aspartimide formation during peptide synthesis remains a formidable challenge. Aspartimide formation leads to low yields in addition to costly purification or even inaccessible peptide sequences. Here, we report an
