Anwendungen

Tris(2-aminoethyl)amine is a tetradentate chelating ligand and forms stable complexes with transition metals. It is also used as a carbon dioxide absorbent. Further, it acts as a reagent for cleavage of the fluorenylmethyloxycarbonyl (Fmoc) group in peptide synthesis. It reacts with aryl isocyanates and isothiocyanates to give tris-urea and -thiourea derivatives.

Bemerkungen

Air sensitive and hygroscopic. Store in a cool place. Incompatible with strong acids and strong oxidizing agents.

Literaturverweise

Reagent for rapid cleavage of the Fmoc group in peptide synthesis, particularly recommended in conjunction with Fmoc-protected acid chlorides as the active species: J. Org. Chem., 55, 1673 (1990). For a review of peptide synthesis via amino acid halides, see: Acc. Chem. Res., 29, 268 (1996). For peptide reagents, see Appendix 6.

Reaction with aryl isocyanates and isothiocyanates gives tris-urea and -thiourea derivatives which have been evaluated as phosphate and sulfate receptors: Chem. Lett., 759 (1995).
