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.

Bazanov, Daniil R. published the artcile2,4,5-Tris(alkoxyaryl)imidazoline derivatives as potent scaffold for novel p53-MDM2 interaction inhibitors: Design, synthesis, and biological evaluation, Application In Synthesis of 86-51-1, the main research area is design synthesis biol evaluation trisalkoxyarylimidazoline p53 MDM2 interaction inhibitor; Anticancer; Fragmentary approach; Imidazolines; Nutlin analogues; Synthetic design.

Imidazoline-based small mol. inhibitors of p53-MDM2 interaction intended for the treatment of p53 wild-type tumors are the promising structures for design of anticancer drugs. Based on fragment approach we have investigated a key role of substituents in cis-imidazoline core for biol. activity of nutlin family compounds Although the necessity of the substituents in the Ph rings of cis-imidazoline has been shown, there are no studies in which the replacements of a halogen by other substituents have been investigated. A series of simple cis-imidazoline derivatives containing halogen, hydroxy and alkoxy-substituents were synthesized. The biol. activity of the compounds was studied using assays of cytotoxicity (MTT) and p53 level. It was found that the hydroxyl-derivatives were not cytotoxic whereas the alkoxy analogs were the same or more active as halogen-substituted compounds in cell viability test. The synthesized alkoxy derivatives induced an increase of p53 level and did not promote necrotic cell death in the concentration up to 40 μM.

Chen, Qinfang published the artcileConstruct indeno[1,2-b]oxepine or cis-cyclopropylacrylate by sulfur ylides, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is indenooxepine preparation; malononitrile aldehyde crotonate derived sulfur ylide annulation; cyclopropyl acrylate diastereoselective preparation; arylideneindenedione aldehyde crotonate derived sulfur ylide annulation.

For the first time, the [4 + 3] or [2 + 1] annulation of crotonate-derived sulfur ylides with arylidenemalononitrile or arylidene-1H-indene-1,3(2H)-dione was reported using Na2CO3 as the base. This protocol was advantageous as it does not require prior preparation of arylidenemalononitrile or arylidene-1H-indene-1,3(2H)-dione substrates, due to the independent participation of the base in the two reactions. This mild, operationally multicomponent process could be employed for the transformation of a wide variety of com. available aldehydes into the corresponding indeno[1,2-b]oxepines I [R = H, 4-CNC6H4, 2-OMeC6H4, etc.; R1 = Me, Et] or cyclopropyl acrylate core II in moderate to excellent yields under mild conditions.

Evdokimov, Nikolai M. published the artcileOne-Step, Three-Component Synthesis of Pyridines and 1,4-Dihydropyridines with Manifold Medicinal Utility, Formula: C11H12O3, the main research area is aldehyde thiol malononitrile cyclization pyridine enamino nitrile preparation.

Privileged medicinal scaffolds based on the structures of 2-amino-3,5-dicyano-6-sulfanylpyridines and the corresponding 1,4-dihydropyridines have been prepared via a single-step, three-component reaction of structurally diverse aldehydes with various thiols and malononitrile. Mechanistic studies revealed that 1,4-dihydropyridines undergo oxidation by the intermediate Knoevenagel adducts rather than by air oxygen. Although the latter process undermines the yields of pyridines, it results in the formation of substituted enamino nitriles, promising antiinflammatory agents.

Sheng, Min published the artcileSingle-Crystal Cobalt Phosphide Nanorods as a High-Performance Catalyst for Reductive Amination of Carbonyl Compounds, Related Products of isoquinoline, the main research area is cobalt phosphide nanorod preparation surface structure; aldehyde ammonia cobalt phosphide nanocatalyst reductive amination green chem; ketone ammonium acetate cobalt phosphide reductive amination green chem; primary amine preparation.

Herein, the successful synthesis of single-crystal cobalt phosphide nanorods (Co2P NRs) containing coordinatively unsaturated Co-Co active sites, which serve as a new class of air-stable, highly active, and reusable heterogeneous catalysts for the reductive amination of carbonyl compounds was reported. The Co2P NR catalyst showed high activity for the transformation of a broad range of carbonyl compounds to their corresponding primary amines using an aqueous ammonia solution or ammonium acetate as a green amination reagent at 1 bar of H2 pressure; these conditions were far milder than previously reported. The air stability and high activity of the Co2P NRs was noteworthy, as conventional Co catalysts were air-sensitive (pyrophorous) and show no activity for this transformation under mild conditions. P-alloying was therefore of considerable importance for nanoengineering air-stable and highly active non-noble-metal catalysts for organic synthesis.

Ran, Xiaoyun published the artcileA novel route to unsymmetrical disubstituted ureas and thioureas by HMPA catalyzed reductive alkylation with trichlorosilane, Product Details of C2H6N2O, the main research area is unsym disubstituted urea preparation chemoselective; aldehyde monosubstituted urea reductive alkylation HMPA catalyst; ketone monosubstituted urea reductive alkylation HMPA catalyst; disubstituted thiourea unsym preparation chemoselective; monosubstituted thiourea aldehyde reductive alkylation HMPA catalyst; thiourea monosubstituted ketone reductive alkylation HMPA catalyst.

An hexamethylphosphoramide (HMPA) catalyzed reductive alkylation of ureas and thioureas with trichlorosilane under mild reaction conditions was developed. Both aldehydes and ketones could be used as efficient alkylation reagents in this method to obtain unsym. disubstituted ureas R1NHC(O)NHR2 [R1 = n-Pr, cyclohexyl, Bn, etc.; R2 = Me, Ph, PhC(O), etc.] and thioureas R3NHC(S)NHR4 [R3 = n-Pr, Bn, CH2CH=CHPh, etc.; R4 = Me, Ph, 4-MeOC6H4, 4-FC6H4] in moderate to high yields. A variety of di- and trisubstituted ureas and thioureas were easily prepared by this new reductive alkylation method.

Shaabani, Shabnam published the artcileAutomated and accelerated synthesis of indole derivatives on a nano-scale, Product Details of C9H10O3, the main research area is indoline diversity oriented nano scale synthesis; cyclic Schiff base in situ preparation Ugi type reaction; phenyl hydrazine aldehyde Fischer indolization.

For the first time use of acoustic droplet ejection technol. and fast quality control was described to screen the efficiency of synthetic reactions on a nanomole scale in an automated and miniaturized fashion. The interrupted Fischer indole combined with Ugi-type reactions yielded several attractive drug-like indole scaffolds such as I [R1 = H, 5-Me, 4,6-di-Me, 5-MeO, 7-Br; R2 = Me, Et, ; R3 = Me, Et; R2R3 = (CH2)5, (CH2)2O(CH2)2, (CH2)2NBoc(CH2)2; R4 = i-Pr, cyclohexyl, 4-MeOC6H4, etc.; R5 = t-Bu, 2-pyrrolyl, 2-indolyl, etc.], tetrazole II and imino hadantoin e.g., III. In 384-well plates, a diverse set of interrupted Fischer indole intermediates were produced and reacted with the tricyclic hydantoin backbone in a 2-step sequence. Similarly, preformed Fischer indole intermediates were used to produce diverse sets of Ugi products and the efficiency was compared with that of the in situ method. Multiple reactions were performed again on a preparative millimole scale, showing scalability from nano to mg and thus synthetic utility. An unprecedented large number of building blocks were used for fast scope and limitation studies (68 isocyanides, 72 carboxylic acids). Miniaturization and anal. of the generated big synthesis data enabled deeper exploration of the chem. space and permitted the gain of knowledge that was previously impractical or impossible, such as the rapid survey of reactions and building block and functional group compatibility.
