Beschreibung

Allgemeine Beschreibung

Fmoc-Aaa-(Dmb)Gly-OH dipeptides offer the same benefits as pseudoproline dipeptides in Fmoc SPPS 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. This derivative also completely inhibits aspartimide formation.
