Applicazioni

Pentafluorophenol is used in the preparation of pentafluorophenyl esters for peptide synthesis and vulcanized polymers. It is also used for peptide coupling and heterocyclic acid derivatives. It is involved in the preparation of pentafluorophenyl formate which acts as a formulating agent for amines and amino acids.

Note

Moisture sensitive. Incompatible with strong oxidizing agents, bases, acid chlorides and acid anhydrides.

Letteratura

Widely used for peptide coupling (see Appendix 6) via the active PFP esters, generally prepared by carbodiimide coupling: Liebigs Ann. Chem., 1421 (1973); Tetrahedron Lett., 1785 (1974). With Fmoc-protected amino acids, the coupling takes place very rapidly, which reduces the amount of Fmoc-cleavage during the peptide bond formation: Synthesis, 325 (1983). Fmoc protected PFP esters have also been applied in solid phase peptide synthesis: Tetrahedron, 44, 843 (1988). PFP esters have been recommended for preparation of derivatives of heterocyclic acids, effective where DCC or DIC alone fail: Synth. Commun., 28, 753 (1998).

For preparation and use of the moderately stable PFP formate as a formylating agent for amines and amino acids, see: Synthesis, 510 (1987).
