A mild, general and efficient method for the direct synthesis of diverse amides from commercially available carboxylic acids and isothiocyanates has been developed. The strategy does not require stoichiometric amounts of coupling reagents or metal catalysts, and is especially for sterically hindered and electron-deficient secondary amides, which are otherwise challenging to synthesize.

Key words: amides, carboxylic acids, isothiocyanates, synthetic methods, electron-deficient amides
