Zhang, Xiaofeng published the artcileElectrochemical Tandem Olefination and Hydrogenation Reaction with Ammonia, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is ester nitrile preparation; aldehyde ketone electrochem Horner Wadsworth Emmons hydrogenation tandem reaction.

An electrochem. Horner-Wadsworth-Emmons/hydrogenation tandem reaction was achieved using ammonia as electron and proton donors. The reaction could give two-carbon-elongated ester and nitrile from aldehyde or ketones directly. This reaction could proceed with a catalytic amount of base or even without a base. The ammonia provides both the electron and proton for this tandem reaction and enables the catalyst-free hydrogenation of an α,β-unsaturated HWE intermediate. More than 40 examples were reported, and functional groups, including heterocycles and hydroxyl, were tolerated.

Zhu, Quan published the artcileSaegusa Oxidation of Enol Ethers at Extremely Low Pd-Catalyst Loadings under Ligand-free and Aqueous Conditions: Insight into the Pd(II)/Cu(II)-Catalyst System, Product Details of C11H12O3, the main research area is unsaturated aldehyde preparation; enol ether preparation Saegusa oxidation palladium catalyst.

A highly efficient and practical Pd(II)/Cu(OAc)2-catalyst system of Saegusa oxidation, which converts enol ethers to the corresponding enals with a number of diverse substrates at extremely low catalyst loadings (500 mol ppm) under ligand-free and aqueous conditions, is described. Its synthetic utility was demonstrated by large-scale applications of the catalyst system to important nature mols. This work allows Saegusa oxidation to become a highly practical approach to preparing enals and also suggests new insight into the Pd(II)/Cu(II)-catalyst system for dehydrogenation of carbonyl compounds and decreasing Pd-catalyst loadings.

Zhu, Longfei published the artcileSupported Iridium Catalyst for Clean Transfer Hydrogenation of Aldehydes and Ketones using Methanol as Hydrogen Source, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is zinc oxide support iridium nanocatalyst preparation; alc green preparation iridium nanocatalyst zinc oxide support; aldehyde ketone transfer hydrogenation iridium nanocatalyst methanol hydrogen donor.

The use of methanol as an abundant and low-toxic hydrogen source under mild and clean conditions is promising for the development of safe and sustainable reduction processes, but remains a daunting challenge. This work presents a recyclable ZnO-supported Ir catalyst for the additive-free transfer hydrogenation of aldehydes and ketones using methanol as the hydrogen source at 110°C, delivering alcs. in up to 98% yield. Mechanistic studies disclose that methanol was first dehydrogenated to formaldehyde and then fully decomposed into an active hydrogen species for hydrogenation. The superior performance is related to the high ratio of pos. charged IrOx species and their ultrafine dispersion over ZnO. And the delicate cooperation of IrOx and ZnO enhances the catalytic activities for the selective scission of O-H and less reactive C-H bonds in methanol, maintaining a good balance between methanol decomposition and C=O hydrogenation in this green transfer hydrogenation.

Evdokimov, Nikolai M. published the artcileOne-Step Synthesis of Heterocyclic Privileged Medicinal Scaffolds by a Multicomponent Reaction of Malononitrile with Aldehydes and Thiols, Recommanded Product: 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is heterocyclic privileged medicinal scaffold preparation; multicomponent reaction malononitrile aldehyde thiol; pyridine dihydropyridine chromenopyridine dithiepine preparation.

Heterocyclic privileged medicinal scaffolds involving pyridine, 1,4-dihydropyridine, chromeno[2,3-b]pyridine, and dihydro-1,4-dithiepine frameworks are prepared via a single-step multicomponent reaction of structurally diverse aldehydes with various thiols and malononitrile. Mechanistic studies of the synthetic pathway leading to pyridines reveal that 1,4-dihydropyridines undergo oxidation by the intermediate Knoevenagel adducts rather than by air oxygen. The use of o,o’-disubstituted aromatic aldehydes leads to the corresponding 1,4-dihydropyridines, whereas salicylic aldehydes result in chromeno[2,3-b]pyridines. Reactions of ethanedithiol as a thiol component produce dimeric pyridines with sterically unencumbered aldehydes, while o,o’-disubstituted aromatic aldehydes give dihydro-1,4-dithiepines. Thus, depending on the aldehyde and thiol types, diverse libraries of medicinally relevant compounds can be prepared by a simple one-step process involving no chromatog.

Maazaoui, Radhouan published the artcileDomino Methylenation/Hydrogenation of Aldehydes and Ketones by Combining Matsubara’s Reagent and Wilkinson’s Catalyst, Safety of 2-Methyl-3-(3,4-methylenedioxyphenyl)propionaldehyde, the main research area is domino methylenation hydrogenation aldehyde ketone Matsubara reagent Wilkinson catalyst.

The methylenation/hydrogenation cascade reaction of aldehydes or ketones through a domino process involving two ensuing steps in a single pot is realized. The compatibility of Matsubara’s reagent and Wilkinson’s complex give a combination that allows, under dihydrogen, the transformation of a carbonyl function into a Me group. This new method is suitable to introduce an Et motif from aromatic and aliphatic aldehydes with total chemoselectivity and total retention of α-stereochem. purity. The developed procedure is also extended to the introduction of Me groups from ketones.
