Aromatic Amide - an overview | ScienceDirect Topics
Aromatic amides, generated from acids or acid halides, react with solutions of bromine or chlorine in sodium hydroxide to yield amines through a reaction known as the Hofmann rearrangement (Equation (38)) <46OR (3)267, 49JA3929>.

24.1: Structural, Physical, and Spectral Characteristics of Amides
2021年7月31日 · The NMR spectra of amides are revealing as to the structure of the amide group. For example, the spectrum of \(\ce{N}\),\(\ce{N}\)-dimethylmethanamide shows two three-proton single resonances at \(2.78 \: \text{ppm}\) and \(2.95 \: \text{ppm}\), which means that at ordinary temperatures the two methyl groups on nitrogen are not in the same ...
Amide - Wikipedia
Amides are organic compounds with the formula R−C (=O)−NR′R″, where R, R', and R″ are any groups. They are widely found in nature and technology, such as proteins, plastics, drugs and solvents. Learn about their structure, bonding, basicity, hydrogen bonding and solubility.

2006年10月24日 · Aromatic amide foldamers constitute a growing class of oligomers that adopt remarkably stable folded conformations. The folded structures possess largely predictable shapes and open the way toward the design of synthetic mimics of proteins.
Amides may also be sub-classified as aliphatic, aromatic (i.e. anilides or benzamides) or cyclic (lactams), based on the nature of the nitrogen substituents and overall structure. Aliphatic amides have simple hydrocarbon substituents (alkyl groups) while aromatic amides have at least aromatic ring substituent as shown in the example below.

2024年9月7日 · Characterization of spherical amides 2 Compound 2 was characterized by 1 H NMR (see ESI† for details) and X-ray crystallographic analysis. 1 H NMR spectra of 2b showed that all the aromatic protons on the four benzene rings of the core structure appeared to be non-equivalent in the high magnetic region (6.5–7.0 ppm) because of the symmetry of its structure, i.e., the point group of the ...

Like polyhydroxyproline and β-peptides, these oligomers localize to the cytosol and nucleus of live cells. Unlike these molecules, however, the aromatic amides do not require sequestration of the positively charged groups along a specific region of the helix.
