CAS号 Hill配方 摩尔质量 207305-95-1 C₂₈H₂₇NO₆ 473.52 g/mol 描述 概述 Quasi-orthogonally-protected Asp derivative.
The 2-PhiPr group can be removed selectively in the presence of tBu-based protecting groups by treatment with 1% TFA in DCM [1], making this derivative an extremely useful tool for the preparation of cyclic peptides by Fmoc SPPS [2] or for library synthesis. For the on-resin synthesis of side-chain to side-chain lactam bridged peptides, the combination of Lys(Mtt) and Asp(O-2-PhiPr) is particularly advantageous since both side-chains can be simultaneously unmasked in a single step.
This protecting group has also been used in solution to prepare bicyclic helix initiating peptides [3, 4].产品目录编号 852335 品牌系列 Novabiochem®
