Fmoc-Lys(Boc)-(Dmb)Gly-OH

Fmoc-Aaa-(Dmb)Gly-OH dipeptides offer the same benefits aspseudoproline dipeptides such as prevention of aggregation and improvements in product quality but for peptide sequences containing Gly. They are extremely easy to use. Standard coupling methods like PyBOP^®/DIPEA or DIPCDI/HOBt can be used for their introduction. Removal of the Dmb group and regeneration of the glycine residue occurs during the course of standard TFA-mediated cleavage reaction.
