diethylaminosulfur trifluoride - coupling reagents - amino acyl fluorides - fluorination

Significance

The development of rapid, practically simple, and cost-effective methods for the synthesis of activated amino acids is a highly demanding field in the peptide industry. In 1996, Kaduk and co-workers reported a rapid and practically simple method for the conversion of Fmoc-amino acids into Fmoc-amino acyl fluorides with the help of (diethylamino)sulfur trifluoride.

Comment

(Diethylamino)sulfur trifluoride (DAST) is one of the efficient reagents for the rapid conversion of Fmoc-amino acid into the corresponding Fmoc-amino acyl fluorides in good yields and with high purity. This method is practically simple and involves simple recrystallization or precipitation for the purification of Fmoc-amino acyl fluorides.
