AbstractAn efficient and inexpensive procedure for direct conversion of aliphatic carboxylic acids into amides has been developed using anilines or aliphatic amines and Mg(0) as catalyst in toluene. The amides were obtained by single crystallization in moderate to excellent yields with high purity. Graphical Abstract

Furan heterocyclic compoundsderivedfrom renewable sources are popular versatile candidates for the production of multifunctional macromolecular materials. These compounds are also used as hydrophobilization monomers for reversible polyadducts or as versatile building blocks in Diels-Alder reactions. In the present study, an efficient approach to chemoselective acylation of furfurylamine with a series
