The construction of amide bonds and peptide linkages is one of the most fundamental transformations in all life processes and organic synthesis. The synthesis of structurally ubiquitous amide motifs is essential in the assembly of numerous important molecules such as peptides, proteins, alkaloids, pharmaceutical agents, polymers, ligands and agrochemicals. A method of SO2F2-mediated direct clickable coupling of carboxylic acids with amines was developed for the synthesis of a broad scope of amides in a simple, mild, highly efficient, robust and practical manner (>110 examples, >90% yields in most cases). The direct click reactions of acids and amines on a gram scale are also demonstrated using an extremely easy work-up and purification process of washing with 1 M aqueous HCl to provide the desired amides in greater than 99% purity and excellent yields.

Aminocarbonylation of aryl iodides with primary and secondary aromatic/aliphatic amines to corresponding amides using polymer supported palladium-N-heterocyclic carbene complex (PS-Pd-NHC) as an efficient heterogeneous, recyclable catalyst is described. The catalytic system was optimized with respect to various reaction parameters to give excellent yield of desired products. The catalyst can be easily separated by simple filtration process and recycled further up to four consecutive recycle without loss in any activity and selectivity. The protocol is advantageous due to the ease in handling of the catalyst, simple workup procedure, and environmentally benign water as solvent and effective catalyst recyclability.
Two efficient N-acylation methods mediated by solid-supported reagents for weakly nucleophilic heterocyclic amines
