The methoxy-, hydroxy-, and carbonyl-substituted benzenes are the simplest fragments from the lignin separation feedstocks. Extensive experimental thermochemical studies of these compounds were carried out, including combustion calorimetry, vapor pressure measurements, and differential scanning calorimetry. We have collected available primary experimental results on enthalpies of formation and vapor pressures as well as on phase transitions, liquid-gas, liquid-solid, and crystal-liquid. These data were evaluated using empirical, semiempirical, and quantum chemical methods. The consistent sets of evaluated thermodynamic data were used to design the method for predicting enthalpies of vaporization and enthalpies of formation of di- and trisubstituted benzenes. It is expected that parameters and pairwise interactions will be transferable to predict the thermochemical properties of poly methoxy-substituted and poly hydroxysubstituted benzenes that appear in reaction products of lignin transformations in the value-adding chemicals and materials.

Product Details of 93-02-7. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7

A facile three-component reaction of aromatic aldehyde, 2,2-dimethyl-1,3-dioxane-4,6-dione, and 6-amino-1,3-dimethyluracil was developed for the first time using beta-cyclodextrin (beta-CD) as a macrocyclic host for aldehyde and an efficient catalyst that leads to a batch of novel pyrano[2,3-d:6,5-d ‘]dipyrimidines (4a-k). The synthesis was accomplished with the aid of microwave irradiations in solvent-free conditions. The product obtained was in contrast to the previous report in which a similar reaction resulted in a mixture of benzylidenepyrimidine and bisaminopyrimidine analogs in the presence of triethylbenzylammonium chloride in an aqueous medium. The formation of the pyrano[2,3-d:6,5-d ‘]dipyrimidines may be in virtue of the property of beta-CD to construct new C-C and C-X (where X = heteroatom) bonds. Reusability of the catalyst up to three runs without any noteworthy change in catalytic activity is one of the main features of the reaction. Other noteworthy features are good to excellent yields, eco-friendly procedure, non-column chromatographic purification, and mild conditions.

An efficient and BF3 center dot Et2O-catalyzed chemoselective synthesis of diversified 1,3-diarylisobenzofuran in a high yield has been described. The reaction proceeds through sequential hydroarylation-cyclization between 2-formylarylketones and electron-rich arenes/heteroarenes. Advantageous features of the developed methodology include operational simplicity, a broad substrate scope, and applicability towards gram scale synthesis. The utility of isobenzofuran derivatives as the diene was extended to the synthesis of [4+2] cyclo-adducts with DMAD and the synthesis of 1,2-dicarbonylarenes in good yields.

Recommanded Product: Benzoic anhydride. I found the field of Chemistry very interesting. Saw the article Influence of the reducing-end anomeric configuration of the Man(9)epitope on DC-SIGN recognition published in 2020, Reprint Addresses Ramos-Soriano, J; Rojo, J (corresponding author), Univ Seville, CSIC, Glycosyst Lab, Inst Invest Quim IIQ, Av Amer Vespucio 49, Seville 41092, Spain.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride.

High-mannose (Man(9)GlcNAc(2)) is the main carbohydrate unit present in viral envelope glycoproteins such as gp120 of HIV and the GP1 of Ebola virus. This oligosaccharide comprises the Man(9)epitope conjugated to two terminalN-acetylglucosamines by otherwise rarely-encountered beta-mannose glycosidic bond. Formation of this challenging linkage is the bottleneck of the few synthetic approaches described to prepare high mannose. Herein, we report the synthesis of the Man(9)epitope with both alpha and beta configurations at the reducing end, and subsequent evaluation of the impact of this configuration on binding to natural receptor of high-mannose, DC-SIGN. Using fluorescence polarization assays, we demonstrate that both anomers bind to DC-SIGN with comparable affinity. These relevant results therefore indicate that the more synthetically-accesible Man(9)alpha epitope may be deployed as ligand for DC-SIGN in bothin vitroandin vivobiological assays.

A simple and efficient methodology for Friedel-Crafts acylation of 3-methylindole using Amberlyst 15 resin as catalyst is described. This methodology shows good selectivity towards the formation of the products of 2-acylation, (3-methyl-1H-indol-2-yl)ketones. Several advantages can be ascribed to Amberlyst 15, among them; are the ease of handling, quick separation from the reaction mixture and minimum or no production of the chemical residues that must be eliminated. Besides, the catalyst can be easily recycled and reused with a minimal loss in activity through 6 reaction cycles. The catalyst was characterized by FT-IR spectroscopy and superficial acidity.

The electrochemical-induced C-H methylthiolation of electron-rich aromatics has been accomplished via a three component cross-coupling strategy. Potassium thiocyanate (KSCN) as both the supporting electrolyte and sulfur source and methanol as the methylation reagent are used. This protocol is versatile for various (hetero)aromatic compounds such as aniline, anisole and indole. The reaction proceeds under mild conditions without any metal catalyst, exogenous oxidant and highly toxic sulfur reagent. Importantly, such an electrochemical-induced methylthiolated reaction could be easily scaled up with good efficiency.

A simple, facile and efficient method has been developed for the Friedel-Crafts benzoylation of arenes using magnetic gamma-Fe2O3 nanoparticles under solvent-free sonication. The gamma-Fe2O3 nanoparticles were used as an efficient and magnetically recoverable catalyst for the synthesis of aromatic ketones in good to excellent yields at room temperature under solvent-free. The reaction occurred with high regioselectivity under mild condition. The magnetic gamma-Fe2O3 nanoparticles are economically synthesized in large-scale, easily separated from the reaction mixture by an external magnet and able to be reused several times without significant loss of the catalytic performance, which make them easy application to industrial processes.

Three-component reaction of methyl 4-aryl-2,4-dioxobutanoates with aromatic aldehyde and 2-aminoacetonitrile sulfate in glacial acetic acid in the presence of anhydrous sodium acetate afforded previously unknown (3-aroyl-2-aryl-4-hydroxy-5-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetonitriles. The reaction involved intermediate formation of Schiff base, followed by Michael-type addition of the dioxo ester to the C=N bond and cyclization of the addition product, methyl 3-aroyl-4-aryl-4-(cyanomethylamino)-2-oxobutanoate. The cyclization product reacted with hydrazine hydrate at the aroyl carbonyl group to give the corresponding hydrazone which was converted in 1,4-dioxane to the cyclic form, [3,4-diaryl-6a-hydroxy-6-oxo-3a,4,6,6a-tetrahydropyrrolo[3,4-c]pyrazol-5(1H)-yl]acetonitrile, without elimination of the second water molecule. When the reaction of (3-aroyl-2-aryl-4-hydroxy-5-oxo-2,5-dihydro-1H-pyrrol-1-yl)acetomtriles with hydrazine hydrate was carried out in boiling acetic acid, [3,4-diaryl-6-oxo-2,6-dihydropyrrolo[3,4-c]pyrazol-5(4H)-yl]acetonitriles were obtained as a result of dehydration of initially formed [3,4-diaryl-6a-hydroxy-6-oxo-3a,4,6,6a-tetrahydropyrrolo[3,4-c]pyrazol-5(1H)-yl]acetonitriles as shown by special experiment. The structures of [6a-hydroxy-6-oxo-3,4-diphenyl-3a,4,6,6a-tetrahydropyrrolo[3,4-c]pyrazol-5(1H)-yl]acetonitrile and [4-(4-methoxyphenyl)-6-oxo-3-phenyl-2,6-dihydropyrrolo[3,4-c]pyrazol-5(4H)-yl]acetonitrile were determined by X-ray analysis.
