Abstract: The present review offers an overview of nonclassical (e.g., with no pre- or in situ activation of a carboxylic acid partner) approaches for the construction of amide bonds. The review aims to comprehensively discuss relevant work, which was mainly done in the field in the last 20 years. Organization of the data follows a subdivision according to substrate classes: catalytic direct formation of amides from carboxylic and amines (section 2); the use of carboxylic acid surrogates (section 3); and the use of amine surrogates (section 4). The ligation strategies (NCL, Staudinger, KAHA, KATs, etc.) that could involve both carboxylic acid and amine surrogates are treated separately in section 5.

Anilide Formation from Thioacids and Perfluoroaryl Azides
TL;DR: The reaction proved highly efficient, displaying fast kinetics, high yield, and good chemoselectivity, and it showed high performance in polar protic/aprotic media, including aqueous buffer systems.
On the two-component microwave-mediated reaction of isonitriles with carboxylic acids: regarding alleged formimidate carboxylate mixed anhydrides.
TL;DR: The formimidate carboxylate mixed anhydride (FCMA) is proposed as the reactive intermediate, which undergoes 1,3-O-->N acyl transfer to give the observed product.
Chemoselectivity in chemical biology: acyl transfer reactions with sulfur and selenium.
TL;DR: The traceless Staudinger reaction has been developed as a means for immobilizing proteins on a solid support, providing a general method of fabricating microarrays that display proteins in a uniform orientation and has made proteins more readily accessible targets for chemical synthesis and semisynthesis.
Synthesis of novel S-neoglycopeptides from glycosylthiomethyl derivatives.
TL;DR: One type of neoglycopeptides was obtained via reaction of glycosylthiomethyl bromide with cysteine and homocysteine containing peptide derivatives, thus affording the corresponding S-(glycosyl ThiometHyl) peptides.
Microwave‐Assisted Aminocarbonylation of Ynamides by Using Catalytic [Fe3(CO)12] at Low Pressures of Carbon Monoxide
TL;DR: A new class of (E)-acrylamides that are potentially suitable for several applications has been regioselectively synthesized after microwave irradiation for only 20 min by using eco-friendly [Fe(3)(CO)(12)] as the catalyst precursor and triethylamine as the ligand.
