Aliphatic acid amides of the fruits of Zanthoxylum piperitum

Phytochemistry, 2004
Six aliphatic acid amides (1-6) were isolated from the pericarp of Zanthoxylum piperitum fruits. MS and NMR spectroscopic investigation revealed that these compounds have a ketone and/or hydroxyl group(s) in the unsaturated aliphatic acid moiety of the structure of the amides.

Selective α‐Oxyamination and Hydroxylation of Aliphatic Amides

Angewandte Chemie - International Edition, 2017
Abstract Compared to the α‐functionalization of aldehydes, ketones, even esters, the direct α‐modification of amides is still a challenge because of the low acidity of α‐CH groups. The α‐functionalization of N−H (primary and secondary) amides, containing both an unactived α‐C−H bond and a competitively active N−H bond, remains elusive.

Cu-catalysed transamidation of unactivated aliphatic amides

Organic & Biomolecular Chemistry, 2022
Direct transamidation is gaining prominence as a ground-breaking technique that generates a wide variety of amides without the requirement of acid–amine coupling or other intermediate steps.

The basicities of aliphatic amides

Australian Journal of Chemistry, 1983
We report pKa values in aqueous solution at 298 K of the protonated forms of several aliphatic amides, viz., acetamide (pKa = -0.62 ± 0.07), N -methylacetamide (-0.42 ± 0.03), N,N -dimethyl-acetamide (-0.28 ± 0.03), N,N -dimethylformamide (-1.2 + 0.5), urea (0.053 ± 0.002) and thiourea (-0.9 ± :O.l).

Thermodynamics of protonation and hydration of aliphatic amides

Journal of the Chemical Society, Perkin Transactions 2, 1993
The protonation equilibria of a series of aliphatic amides of the type R–CO–NH2, R–CO–NHCH3 and R–CO–N(CH3)2(R = H, Me. Et, Pri, But) have been studied in aqueous H2SO4 in the temperature range 25–60 °C, thus determining the protonation (m* and pK) and the thermodynamic parameters of the ionization equilibrium (ΔG°, ΔH°, ΔS°).
