    Project supported by the National Natural Science Foundation of China (Nos. 21602055, 21302048), the Science and Technology Innovative Research Team in Higher Educational Institutions of Hunan Province (No. 2012-318) and the Construct Program of the Key Discipline in Hunan Province.

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
