Amide–Amide Hydrogen Bonding. Semirubin Amides
Monatshefte für Chemie - Chemical Monthly, 2006Semirubins are analogs for one-half of the bilirubin structure and capable of intramolecular hydrogen bonding. Semirubin amides of ammonia and primary amines are also capable of intramolecular hydrogen bonding. From a combination of spectroscopic methods (1H NMR, NOE, and VPO), the primary amide is found to engage very effectively in intramolecular ...

Many hormones, neurotransmitters and growth factors are peptides that carry an amide group at their carboxyl terminus which is essential for their biological activity. The amide is formed by hydroxylation of an additional glycine residue present in the biosynthetic precursor and the hydroxyglycine derivative dissociates to form the peptide amide and ...

This chapter discusses enamines. It explains the process of achieving enamine through regaining neutrality by losing a proton adjacent to the iminium moiety. Additionally, these compounds rarely serve as nucleophiles or bases on nitrogen. The chapter discusses the formation of enamines from amine and aldehyde or ketone.

Methyl Esters as Cross-Coupling Electrophiles: Direct Synthesis of Amide Bonds
ACS Catalysis, 2019Amide bond formation and transition metal-catalyzed cross-coupling are two of the most frequently used chemical reactions in organic synthesis. Recently, an overlap between these two reaction families was identified when Pd and Ni catalysts were ...

Recent Advances in the Metal-Catalyzed Activation of Amide Bonds.
Chemistry - An Asian Journal, 2018The amide functional group is commonly found in peptides, proteins, pharmaceutical compounds, natural products, and polymers. The synthesis of amides is typically performed by using classical approaches that involve the reaction between a carboxylic acid
