Electrochemical Borylation of Carboxylic Acids [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
Significance Boronic acids are one of the most useful functional groups in organic chemistry and can be used as intermediates in synthesis or as key motifs in medicines. This work describes an extremely simple and economical way to use electrochemistry to convert carboxylic acids, through the intermediacy of redox-active esters, to ...

Vibrational Stark Fields in Carboxylic Acid Dimers

open access: yes, 2022
Carboxylic acids form exceptionally stable dimers and have been used to model proton and double proton transfer processes. The stabilization energies of the carboxylic acid dimers are very weakly dependent on the nature of the substitution.

Study on differential expression of 1-aminocyclopropane-1-carboxylic acid oxidase genes in table grape cv. Thompson Seedless [PDF]

open access: yes, 2013
As a consequence of the non-climacteric status of grapes (Vitis vinifera), ethylene biosynthesis and signal transduction have scarcely been studied in this fruit.

The effect of aliphatic carboxylic acids on olfaction-based host-seeking of the malaria mosquito Anopheles gambiae sensu stricto [PDF]

open access: yes, 2009
The role of aliphatic carboxylic acids in host-seeking response of the malaria mosquito Anopheles gambiae sensu stricto was examined both in a dual-choice olfactometer and with indoor traps.

Repurposing amine and carboxylic acid building blocks with an automatable esterification reaction

open access: yes, 2022
New methodologies to unite amines and carboxylic acids that complement the popular amide coupling can significantly expand accessible chemical space because they yield products distinct from the classic R–NHC(O)–R’ amide arrangement.

A Prodigious Behavior of Cycloalkyl Carboxylic Acid to Access 2D Space from 3D Space via Multifold C-H Activation

open access: yes, 2023
The dehydrogenation chemistry has long prevailed in the paradigm of organic synthesis. More common with carbonyl compounds, many classical reactions evolved around it.

Effects of D-amino acid oxidase inhibition on memory performance and long-term potentiation in vivo [PDF]

open access: yes, 2013
N-methyl-d-aspartate receptor (NMDAR) activation can initiate changes in synaptic strength, evident as long-term potentiation (LTP), and is a key molecular correlate of memory formation.

Molecular characterization of cellulose synthase (CesA) genes and impact of mutations on fungicide resistance in oomycetes [PDF]

open access: yes, 2012
Many oomycetes are important pathogens of plants (e.g. arable crops, fruit and forest trees), animals or microbes and, upon attacking their hosts, cause considerable economic damage mainly in agriculture and aquaculture.

Carboxylic acids - snapshot

open access: yes, 2022
A carboxylic acid is an organic acid that contains a carboxyl group (C(=O)OH) attached to an R-group. The general formula of a carboxylic acid is R−COOH or R−CO2H, with R referring to the alkyl, alkenyl, aryl, or other group.

Preparation of New 2,3-Diphenylpropenoic Acid Esters – Good Yields Even for the More Hindered Z Isomers [PDF]

open access: yes, 2004
The potassium salt of E- and Z-2,3-diphenylpropenoic acids prepared in situ could be esterified efficiently in DMSO with the appropriate alkyl halides at room temperature.
