Fmoc-L-glutamic acid 5-tert-butyl ester Chemical Properties,Usage,Production

Description

Fmoc-L-glutamic acid 5-tert-butyl ester is a Fmoc derivative with an N-substituted tert-butyl ester molecule. It is white or gray-white solid crystals at room temperature and pressure, poor solubility in water and insoluble in petroleum ether, but soluble in ethyl acetate, acetic acid and N,N-dimethylformamide.

Chemical Properties

White powder

Uses

Fmoc-Glu(OtBu)-OH (Fmoc-L-glutamic acid 5-tert-butyl ester) can be employed as a:

Ligand in the synthesis of cis-substituted cyclopropane carboxylic acids via C-H activation of cyclopropane carboxamides using Pd catalyst.
Linker in the preparation of multi-small molecule-conjugated PTX (paclitaxel) derivatives.

It can be also used as a building block in the preparation of stapled α-helical peptides , and peptide C-terminal thioesters .

General Description

Fmoc-L-glutamic acid 5-tert-butyl ester is a protected building block used for the introduction of glutamic acid into peptides.
