Fmoc-Glu-ODmab,N-α-Fmoc-L-glutamic acid α-4-{N-[1-(4,4-dimethyl-2,6-dioxocyclohexylidene)-3-methylbutyl]-amino} benzyl ester

一般描述

Quasi-orthogonally-protected Glu 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. For the on-resin synthesis of side-chain to side-chain lactam bridged peptides, the combination of Lys(ivDde) and Glu(ODmab) is particularly advantageous since both side-chains can be simultaneously unmasked in a single step.

The product number for this product was previously 04-12-1174.
