| Fmoc-Lys(Boc)-Thr(psiMe,Mepro)-OH | 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 Lys-Thr dipeptide motif. It consists of a dipeptide in which the threonine residue has been reversibly protected as a structure-breaking proline-like TFA-labile oxazolidine. The reason the 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 threonine residue is regenerated during the normal TFA-mediated cleavage reaction. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-Lys(Boc)-Thr(psiMe,Mepro)-OH. Product Category: Amino Acids. CAS No. 911838-56-7. Mole weight: 609.71. Product ID: ACM911838567-1.

| Fmoc-Lys(Dde)-OH | Quasi-orthogonally-protected Lys derivative for Fmoc SPPS. The Fmoc group can be removed selectively by treatment with piperidine; the Dde group is cleaved with 2% hydrazine in DMF. When removing Dde in the presence of allyl based protecting groups, allyl alcohol should be included in the deprotection solution to prevent reduction of the allyl group. Lys(Dde) has been employed in the following applications: synthesis of branched peptides and di-epitopic peptides ; preparation of MAP core molecules and lipo-MAPs; construction of cyclic peptides , TASP molecules , templates for combinatorial chemistry and synthetic proteins ; preparation of peptides modified at the lysine side-chain.It has been reported that Dde can migrate from the side-chain of Lys to the unprotected side-chain of another Lys residue , and from the β-amino group to the α-amino group of Dpr. In the former instance, this problem can be overcome by using Fmoc-Lys(ivDde)-OH or using DBU/DMF (2:98) for Fmoc group removal.Full orthogonality of Dde with Fmoc has recently been demonstrated when hydroxylamine is used for Dde removal.
