This pseudoproline dipeptide is undoubtedly the most effective and simplest to use tool for overcoming aggregation and enhancing peptide quality in Fmoc SPPS for peptide containing the Asp-Ser dipeptide motif. It consists of a dipeptide in which the serine residue has been reversibly protected as a structure-breaking proline-like TFA-labile oxazolidine. The reason pseudoproline residue is introduced as a dipeptide is because it avoids the need to acylate the hindered oxazolidine nitrogen. This has the added advantage of extending the peptide chain by two residues in one step. The serine residue is regenerated during the normal TFA-mediated cleavage reaction. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-Asp(OtBu)-Ser(psiMe,Mepro)-OH. Product Category: Amino Acids. CAS No. 955048-92-7. Mole weight: 538.59. Product ID: ACM955048927.

Fmoc-?-(2-pyridyl)-Ala-OH is an Fmoc protected alanine derivative that is potentially useful for proteomics studies and solid phase peptide synthesis techniques. Alanine is one of the simplest amino acids - a methyl group as the side chain. This small side chain confers a high degree of flexibility (second only to glycine) when incorporated into a polypeptide chain. The Fmoc group is typically removed with a base such as pyridine - an orthogonal de-protection strategy to the acid labilie Boc group.
