Applicazioni

Cyanuric fluoride acts as a fluorinating agent used in the conversion of carboxylic acids into acyl fluorides. It is used as a precursor for fibre-reactive dyes. It is a specific reagent for tyrosine residues in enzyme. Further, it is involved in the preparation of cyanuric acid by hydrolysis

Note

May precipitate upon storage. Moisture sensitive. Incompatible strong oxidizing agents, strong bases and alcohols.

Letteratura

In combination with pyridine, converts carboxylic acids to acyl fluorides in high yields under mild conditions: Synthesis, 487 (1973). Similarly, protected (Fmoc) amino acids are converted in dichloromethane solution to amino acid fluorides. tert-Butyl ester and ether groups are also stable under these conditions. The resulting acyl fluorides are more stable to water than the corresponding acyl chlorides but are more reactive to amines, thus providing a useful peptide coupling method: J. Am. Chem. Soc., 112, 9651 (1990); Tetrahedron, 50, 5309 (1994); Appendix 6. For use of Fmoc amino acid fluorides in solid-phase peptide synthesis, see: Tetrahedron Lett., 32, 1303 (1991); J. Org. Chem., 59, 3275 (1994). For a review of peptide synthesis via amino acid halides, see: Acc. Chem. Res., 29, 268 (1996).

Carboxylic acids can be converted to alcohols under mild conditions via the acyl fluoride and reduction with NaBH4 in the presence of MeOH. The method can be carried out in one pot and is applicable to N-protected amino acids and peptides for which other reduction methods are unsuitable: J. Org. Chem., 61, 6994 (1996).
