Yes. As both are buiding blocks used in Fmoc-SPPS, our steadily increasing offer of pseudoproline dipeptides and isoacyl dipeptides is filed under “Amino Acid Derivatives”. Click on the tab “Amino Acids” and set the second filter on “Isoacyl Dipeptides” or “Pseudoproline Dipeptides”, respectively. The product contained in the families “Fmoc-Dipeptides” and “Dmb and Hmb Dipeptides” could be of interest as well.
