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.

Synthesis of proteins by native chemical ligation
TL;DR: The technique of native chemical ligation is employable for chemically synthesizing full length proteins as discussed by the authors, which are chemically identical to proteins produced by cell free synthesis, and can be refolded and/or oxidized to form native disulfide-containing protein molecules.
