Popis

General description

Fmoc-Glu(OtBu)-OH is widely used as a building block in peptide synthesis for the protection of amine groups.

Application

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 .
