Fmoc-Asp-OtBu
Selectively protected building block for library synthesis or the preparation of β-aspartyl peptides by Fmoc SPPS. After condensation of the side-chain carboxy with an appropriate amine or alcohol, the β-amino and carboxy functions can be selectively unmasked with 20% piperidine in DMF and 50% TFA in DCM respectively, facilitating the synthesis of branched esters and amides, and lactams and lactones containing the aspartyl unit. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-Asp-OtBu, N-α-Fmoc-L-aspartic acid α-t.-butyl ester. Product Category: Amino Acids. CAS No. 129460-09-9. Molecular formula: C23H25NO6. Mole weight: 411.45. Product ID: ACM129460099. Alfa Chemistry ISO 9001:2015 Certified. Categories: (S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(tert-butoxy)-4-oxobutanoic acid.
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. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-Asp(OtBu)-(Dmb)Gly-OH, N-α-Fmoc-β-O-t.-butyl-L-aspartyl-N-α-(2,4-dimethoxybenzyl)-glycine. Product Category: Amino Acids.

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.
