Reliable Determination of Amidicity in Acyclic Amides and Lactams [PDF]
The Journal of Organic Chemistry, 2012 Two independent computational methods have been used for determination of amide resonance stabilization and amidicities relative to N,N-dimethylacetamide for a wide range of acyclic and cyclic amides. The first method utilizes carbonyl substitution nitrogen atom replacement (COSNAR).

On the relative strengths of amide…amide and amide…water hydrogen bonds
Chemical Physics Letters, 1991We have performed Hayes—Stone intermolecular perturbation theory (IMPT) calculations on amide…water and amide…amide complexes in order to estimate the change ΔW in intermolecular interaction energy associated with the hydrogen bond exchange process amide(NH)…water+water…(OC)amide⇔amide(NH)…(OC)amide+water…water.

Amides IX: Acylation of amides and amines
Recueil des Travaux Chimiques des Pays-Bas, 1952AbstractFurther proofs are adduced in favour of the theory of add catalyzed acylation of amides to diacylamines. Synthetic examples are given partly as improvements of older methods, partly as illustrations of the theory. The preparation of the following new compounds is described: N‐isobutyrylbenzamide, N‐acetyl‐n‐butyramide, N‐methyldipropionimide ...

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 ...

“Amidst the Dust” pays homage to the author’s personal experience conducting research for her MA thesis on Italian-American writer John Fante. Her two months spent in Los Angeles—the city where Fante set many of his literary works—were crucial to developing a richer understanding of Fante’s perception of his identity as a son of Italian immigrants.

Amides II. Acylation of amides to diacylimines
Recueil des Travaux Chimiques des Pays-Bas, 1948AbstractThree acylating mechanisms are involved in the reaction between amides and anhydrides. In the aliphatic series all mechanisms are governed by the inductive effects operating in the reactants.Amides act as acids towards anhydrides.Diacylimines and the corresponding anhydrides acylate alcohols by the same mechanism.A new compound ...
