Carboxylic acids are organic compounds that contain the carboxylic acid functional group, -COOH. They are weak acids with a pungent odor, formed by the oxidation of aldehydes. Carboxylic acids are highly reactive and can readily form esters with alcohols and amides with amines. ...
Aziridine and azirine carboxylic esters : Pure and Applied ChemistryPure & Applied Chemistry
Esterification - Esters are formed by the reaction between an alcohol and either an organic or an inorganic acid. The esterification reaction is undertaken in a reaction column that contains a solid resin catalyst. Click here for reaction, mechanism, typ
Synthesis of higher carboxylic acids using CO2 and H2 is of great importance, because CO2 is an attractive renewable C1 resource and H2 is a cheap and clean reductant. Herein we report a route to produce higher carboxylic acids via reaction of ethers wit
3-dicarbonyl compounds, esters and some carboxylic acid surrogates19,20,21. This can be attributed to both the acidity of the carboxylic acid moiety and the typically high pKavalue of the α-hydrogen. In 1972, Yamada et al.22was the first to report the preparation of α-amino acids from ...
accounting for 16 % of all reactions carried out in medicinal chemistry laboratories.2Amide bonds are typically formed between carboxylic acids and primary amines, secondary amines, or anilines in the presence of condensation reagents such as DCC, EDC, CDI, or HATU. Although these condensation ...
Together, these large gene families of odor-gated ion channels sense a vast number of chemical ligands. Although there is some overlap in ligand tuning, ORs generally respond to esters, alcohols, ketones, and aldehydes, and IRs respond to carboxylic acids and amines (Hallem and Carlson, 2006;...

2-Chloro-4,6-disubstituted-1,3,5-triazines 1 have been widely used in the activation of carboxylic acids in the formation of peptide bonds. The reaction requires the presence of a tertiary amine in the reaction medium and the participation of quaternary triazinyl ammonium salts 2 as ...
- It can be used to prepare pharmacologically active compounds such as antibacterial drugs, anti-tumor drugs and other bioactive molecules. Preparation: Tert-butyl esters of -4-bromoindole-1-carboxylate are usually prepared by reacting 4-bromoindole-1-carboxylic acid with tert-butyl ammonium bromide...
