Mild method for conversion of N-Alkoxyamides to esters using N-Chloro-N-(phenylsulfonyl)benzenesulfonamide

An efficient, fast method for ester synthesis from N-alkoxyamides has been reported. This protocol used easily available N-Chloro-N-(phenylsulfonyl)benzenesulfonamide (NCBSI) for conversion of alkoxy amides to the corresponding esters. The present methodology is metal and ligand-free and takes place under mild reaction conditions. This transformation incorporates a wide variety of amides, prepared from either aryl or alkyl carboxylic acid, leading to the formation of functionalized esters highlighting its ver-satility, chemoselectivity, and high yielding aspects.& COPY; 2023 Elsevier Ltd.
