Synthesis of Acyl Halides from Carboxylic Acid Thioesters for Synthesis of Ketones, Esters, Amides and Peptides

Abstract

AbstractA synthesis of acyl halides from the corresponding carboxylic acid thioesters was achieved using commercially available Selectfluor or NCS, and the acyl fluoride or chloride intermediates were transformed to the corresponding esters, amides, and several carbon‐carbon bond formation products. This approach can be applied to the peptide synthesis from functionalized amino acid thioesters.
