Synthesis of highly alkylated functionalized cyclopentadienes [PDF]

open access: yes, 1988
Tetra- and pentaalkylated cyclopentadienyl ketones and carboxylic acids are prepared by electrophilic allylation of enolizible 1,3-dicarbonyl compounds and successive acid catalyzed ...

Investigating the effectiveness of classical and eco-friendly approaches for synthesis of dialdehydes from organic dihalides

open access: yesGreen Processing and Synthesis, 2019
Monoaldehydes and dialdehydes are parts of millions of compounds and are extremely versatile intermediates. For the synthesis of monoaldehydes, one impressive approach to date, because of its excellent selectivity, high yield and stability towards over ...

Effects of insecticidal ketones present in mint plants on GABA A receptor from mammalian neurons [PDF]

open access: yes, 2017
The genus Mentha, an important member of the Lamiaceae family, is represented by many species commonly known as mint. The insecticidal activity of Mentha oil and its main components has been tested and established against various insects/pests.

Selective oxidation of some primary and secondary benzylic alcohols to the corresponding carbonyl compounds with a Cu(III) complex [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
The selective oxidation of benzylic alcohols to the corresponding carbonyl compounds is described. In alkaline solution, the oxidation reagent potassium tetrasodium diperiodatocuprate(III) dodecahydrate (KNa4[Cu(HIO6)2]×12H2O) reacts with primary and ...

Efficient and Practical Transfer Hydrogenation of Ketones Catalyzed by a Simple Bidentate Mn−NHC Complex [PDF]

open access: yes, 2019
Catalytic reductions of carbonyl‐containing compounds are highly important for the safe, sustainable, and economical production of alcohols. Herein, we report on the efficient transfer hydrogenation of ketones catalyzed by a highly potent Mn(I)−NHC ...

Ketones, omega-3 fatty acids and the Yin-Yang balance in the brain: insights from infant development and Alzheimer’s disease, and implications for human brain evolution★

open access: yesOilseeds and fats, crops and lipids, 2018
Optimal brain performance is intimately linked to the brain’s Yin and the Yang − the balance between its structure and its energy metabolism. This relationship is clearly exemplified in infant brain development and in Alzheimer’s disease, and probably ...

Reactive organoallyl species generated from aryl halides and allene: allylation of alpha,beta-unsaturated aldehydes and cyclic ketones employing Pd/In transmetallation processes [PDF]

open access: yes, 2008
Allylation of α,β-unsaturated aldehydes and cyclic ketones promoted by Pd/In transmetallation processes has been studied. The unsaturated aldehydes underwent regioselective 1,2-addition to afford secondary homoally alcohols.

Alkynes as Synthetic Equivalents of Ketones and Aldehydes: A Hidden Entry into Carbonyl Chemistry

open access: yesMolecules, 2019
The high energy packed in alkyne functional group makes alkyne reactions highly thermodynamically favorable and generally irreversible. Furthermore, the presence of two orthogonal π-bonds that can be manipulated separately enables flexible synthetic ...

Iridium-Catalyzed and pH-Dependent Reductions of Nitroalkenes to Ketones

open access: yesMolecules, 2022
A highly chemoselective conversion of α,β-disubstituted nitroalkenes to ketones is developed. An acid-compatible iridium catalyst serves as the key to the conversion.
