Arylboronic acid and 4-(N,N-dimethylamino)pyridine N-oxide (DMAPO) cooperatively catalyse the dehydrative condensation reaction between carboxylic acids and amines to give the corresponding amides under azeotropic reflux conditions. This cooperative use is much more effective than their individual use as catalysts, and chemoselectively promotes the amide condensation of (poly)conjugated carboxylic acids. The present method is practical and scalable, and has been applied to the synthesis of sitagliptin and a drug candidate.

Samarium diiodide is an efficient Lewis acid type catalyst for the 1,4-addition of aromatic amines onto α,β- unsaturated N-benzoyl amides affording new β-amino amides. These reactions are compared with similar aza-Michael additions involving α,β-unsaturat
