Deoxyfluorinated amidation and esterification of carboxylic acid by pyridinesulfonyl fluoride

Chem Commun (Camb). 2024 Apr 30;60(36):4789-4792. doi: 10.1039/d4cc00877d.

Abstract

Amide bond synthesis is one of the most used reactions in medicinal chemistry. We report an amide bond formation reaction through deoxyfluorinated carboxylic acids under mild conditions using 2-pyridinesulfonyl fluoride. The reaction procedure has been used in a one-pot synthesis of amides and esters via in situ generation of acyl fluoride. This one-pot synthetic method provides easy access to amides and esters. Using this method, we have sequentially synthesized a tetrapeptide and calceolarioside-B glycoside derivative with good yields.
