| | FMOC-ASP-ODMAB Usage And Synthesis |
| Chemical Properties | FMOC-ASP-ODMAB is Yellow powder | | Uses | The Dmab group can be cleaved selectively in the presence of tBu-based protected groups by treatment with 2% hydrazine in DMF, making this derivative an extremely useful tool for the preparation of cyclic peptides by FMOC SPPS | | General Description | Quasi-orthogonally-protected Asp derivative.
The Dmab group can be removed selectively in the presence of tBu-based protecting groups by treatment with 2% hydrazine in DMF [1], making this derivative an extremely useful tool for the preparation of cyclic peptides by Fmoc SPPS or for library synthesis.
Occasionally sluggish cleavage of the aminobenzyl moiety is observed [2, 3]. In these instances, washing the support with 20% DIPEA in DMF/water (9:1) [2] or HCl in dioxane [4] has been found to be efficacious.
For the on-resin synthesis of side-chain to side-chain lactam bridged peptides, the combination of Lys(ivDde) and Asp(ODmab) is particularly advantageous since both side-chains can be simultaneously unmasked in a single step.
To avoid aspartimide formation, it is advisable to employ an Hmb- or Dmb-protected derivative for introduction of the preceding residue.
For applications of this derivative in the synthesis of cyclic peptides, see references [5 - 7].
The product number for this product was previously 04-12-1176.
