I found the field of Chemistry; Science & Technology – Other Topics; Engineering very interesting. Saw the article Highly Efficient Alkylation Using Hydrophobic Sulfonic Acid-Functionalized Biochar as a Catalyst for Synthesis of High-Density Biofuels published in 2019.0. Application In Synthesis of Benzyl Alcohol, Reprint Addresses Deng, Q (corresponding author), Nanchang Univ, Key Lab Poyang Lake Environm & Resource Utilizat, Minist Educ, Sch Resource Environm & Chem Engn, 999 Ave, Nanchang 330031, Jiangxi, Peoples R China.; Deng, Q; Deng, SG (corresponding author), Arizona State Univ, Sch Engn Matter Transport & Energy, 551 E Tyler Mall, Tempe, AZ 85287 USA..

Because H2O decreases the acidity of sulfonic acid-based catalysts and initiates catalytic side reactions, the catalytic activity and selectivity of these catalysts are often unsatisfactory in many reactions that generate H2O as a byproduct. Herein, for the first time, hydrophobic acid-functionalized biochar is prepared by a new route based on a two-step diazo grafting method using 4-aminobenzenesulfonic acid as the sulfonated agent and 4-tert-butylaniline as the hydrophobic agent. The acid density and hydrophobicity can be easily regulated by the amounts of benzenesulfonic acid and tert-butylbenzene groups, respectively. The resulting catalysts have a large specific surface area of 400-700 m(2)/g, high acid density of greater than 2.0 mmol/g, and strong hydrophobicity with an H2O contact angle of up to 136 degrees. Compared with Amberlyst-15 and H2SO4-sulfonated biochar, the hydrophobic acidic biochar exhibits higher activity and selectivity in the alkylation of 4-ethylphenol with phenylmethanol and of 2-methylfuran with cyclic ketones (cyclopentanone and cyclohexanone) for the production of high-density biofuels. The successful preparation of the hydrophobic acidic biochar not only results in an efficient catalyst for reaction systems in which H2O has a deleterious effect but also paves a way for the functional modification of carbonaceous materials.

I found the field of Chemistry very interesting. Saw the article Lewis Acidic Boranes, Lewis Bases, and Equilibrium Constants: A Reliable Scaffold for a Quantitative Lewis Acidity/Basicity Scale published in 2021.0. Safety of 4-Methoxybenzaldehyde, Reprint Addresses Ofial, AR (corresponding author), Ludwig Maximilians Univ Munchen, Dept Chem, Butenandtstr 5-13, D-81377 Munich, Germany.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde

A quantitative Lewis acidity/basicity scale toward boron-centered Lewis acids has been developed based on a set of 90 experimental equilibrium constants for the reactions of triarylboranes with various O-, N-, S-, and P-centered Lewis bases in dichloromethane at 20 degrees C. Analysis with the linear free energy relationship log K-B=LA(B)+LBB allows equilibrium constants, K-B, to be calculated for any type of borane/Lewis base combination through the sum of two descriptors, one for Lewis acidity (LA(B)) and one for Lewis basicity (LBB). The resulting Lewis acidity/basicity scale is independent of fixed reference acids/bases and valid for various types of trivalent boron-centered Lewis acids. It is demonstrated that the newly developed Lewis acidity/basicity scale is easily extendable through linear relationships with quantum-chemically calculated or common physical-organic descriptors and known thermodynamic data (Delta HBF3 ). Furthermore, this experimental platform can be utilized for the rational development of borane-catalyzed reactions.

A metal- and additive-free methodology for the highly selective, photocatalyzed C-H oxygenation of alkylarenes under air to the corresponding carbonyls is presented. The process is catalyzed by an imide-acridinium that forms an extremely strong photooxidant upon visible light irradiation, which is able to activate inert alkylarenes such as toluene. Hence, this is an easy to perform, sustainable and environmentally friendly oxidation that provides valuable carbonyls from abundant, readily available compounds.

A series of azamacrolides containing the carbamate or urea moiety were synthesized and evaluated for their fungicidal activities against several agriculturally important pathogens. In addition, they were investigated for their ability to inhibit quorum sensing in Agrobacterium tumefaciens. The results showed that most of the derivatives had moderate to high fungicidal activities against the tested fungi, especially towards Sclerotinia sclerotiorum. Additionally, D16-19 could be used as a potential broad-spectrum fungicide while D16-4 exhibited a fungicidal activity (EC50 = 1.87 mg L-1) similar to that of carbendazim (EC50 = 1.34 mg L-1) against S. sclerotiorum. The three-dimensional Quantitative Structure-Activity Relationship (3D-QSAR) models were also established based on the experimental results and they would provide valuable information for further optimization. Moreover, D16-17 not only showed a better fungicidal activity against S. sclerotiorum but also had the highest ability to inhibit quorum sensing. These findings suggested that some azamacrolide compounds hold potential for the development of novel fungicides or inhibitors of quorum sensing.

An efficient gram-scale one-pot approach to 2-substituted malonates and related structures is developed, starting from commercially available aldehydes and active methylene compounds. The technique combines Knoevenagel condensation with the reduction of the C=C bond in the resulting activated alkenes with the Zn-AcOH system. The relative ease with which the C=C bond reduction occurs can be traced to the accepting abilities of the substituents in the intermediate arylidene malonates.

We synthesized a set of 13 new and earlier described styrylpyridinium compounds (N-alkyl styrylpyridinium salts with bromide or tosylate anions) in order to evaluate antifungal activity againstC. albicanscells, to assay the possible synergism with fluconazole, and to estimate cytotoxicity to mammalian cells. All compounds were synthesized according to a well-known two-step procedure involving alkylation of gamma-picoline with appropriate alkyl bromide and further condensation with substituted benzaldehyde. Compounds with longN-alkyl chains(C18H37-C20H41) had no antifungal activity against the cells of all testedC. albicansstrains. Other styrylpyridinium compounds were able to inhibit yeast growth at the concentrations of 0.06-16 mu g/ml. At fungicidal concentrations, the compound with the CN- group was least toxic to mammalian cells, showed the most effective synergism with fluconazole, and only slightly inhibited the respiration ofC. albicans. The compound with the 4 ‘-diethylamino group exhibited the strongest fungicidal properties and effectively blocked the respiration ofC. albicanscells. However, toxicity to mammalian cells was also high. Summarizing, the results of our study indicate that styrylpyridinium compounds are promising candidates in the development of new antifungal drugs.

Recently, short synthetic peptides have gained interest as targeting agents in the design of site-specific nanomedicines. In this context, our work aimed at developing new tools for the diagnosis and/or therapy of hepatocellular carcinoma (HCC) by grafting the hepatotropic George Baker (GB) virus A (GBVA10-9) and Plasmodium circumsporozoite protein (CPB)-derived peptides to the biocompatible poly(benzyl malate), PMLABe. We successfully synthesized PMLABe derivatives end-functionalized with peptides GBVA10-9, CPB, and their corresponding scrambled peptides through a thiol/maleimide reaction. The corresponding nanoparticles (NPs), varying by the nature of the peptide (GBVA10-9, CPB, and their scrambled peptides) and the absence or presence of poly(ethylene glycol) were also successfully formulated using nanoprecipitation technique. NPs were further characterized by dynamic light scattering (DLS), electrophoretic light scattering (ELS) and transmission electron microscopy (TEM), highlighting a diameter lower than 150 nm, a negative surface charge, and a more or less spherical shape. Moreover, a fluorescent probe (DiD Oil) has been encapsulated during the nanoprecipitation process. Finally, preliminary in vitro internalisation assays using HepaRG hepatoma cells demonstrated that CPB peptide-functionalized PMLABe NPs were efficiently internalized by endocytosis, and that such nanoobjects may be promising drug delivery systems for the theranostics of HCC.

A new method for the fast synthesis of diverse 4-aryl-6-cycloamino-1,3,5-triazin-2-amines was developed. The synthesis is performed under microwave irradiation in a one-pot manner from cyanoguanidine, aromatic aldehydes, and cyclic amines. Their three-component reaction in the presence of hydrochloric acid produced dihydrotriazines, which were then converted (without isolation) into the targeted compounds via aromatic dehydrogenation in the presence of alkali. The reaction tolerated various aromatic aldehydes (including heterocyclic) and cyclic amities. Crystal structures of two representative 4-aryl-6-morpholino-1,3,5-triazin-2-amines were established by X-ray crystallography. The results of preliminary biological screening identified potent antileukemic activity for 6-[3,4-dihydroisoquinolin-2(1H)-yl]-4- phenyl-1,3,5-triazin-2-amine.

This paper describes the synthesis of polyindole by chemical oxidative polymerization using copper chloride as oxidant. Polyindole was characterized by various spectroscopic techniques like FT-IR, XRD, FESEM, and TGA. The XRD pattern confirms the semi-crystalline nature of polyindole. An efficient, solvent-free, ultrasound-assisted synthesis of biologically active 3,4-dihydropyrimidin-2(1 H)-one/thiones (DHPM) derivatives is reported by using polyindole as a recyclable catalyst. The advantages of this method are mild reaction conditions, short reaction time, excellent yields with high purity and low loading of catalyst. Polyindole can be used several times without loss of significant catalytic activity as compared to the other reported catalysts. Factors affecting on the rate of reaction, like use of ultrasonication, temperature, solvent, amount, and recyclability of catalyst have also been studied.
