The simple and green synthesis of highly substituted furan derivatives containing rare 5-amino-3-aroylfuran moiety

The reaction of potassium 2-aroyl-1,3-dicyano-1,3-bis-methoxycarbonylpropenides with hydrogen peroxide is unusual for compounds of this type and results in formation of highly substituted 5-amino-3-aroylfuran derivatives. In contrast to few related literature methods leading to formation of this moiety, the advantages of this synthesis includes a readily available and inexpensive precursors, non-usage of any toxic reagents or solvents and short process time. The structure of one of the obtained compounds was determined by X-ray diffraction. (C) 2021 Elsevier Ltd. All rights reserved.

Ru-II and Ru-III Chloronitrile Complexes: Synthesis, Reaction Chemistry, Solid State Structure, and (Spectro)Electrochemical Behavior

The synthesis of [Ti6O4(OiPr)(8)(O2CPh)(8)] (3) and [RuCl(N equivalent to CR)(5)][RuCl4(N equivalent to CR)(2)] (4a, R = Me; 4b, R = Ph), [Ru(N equivalent to CPh)(6)][RuCl4(N equivalent to CPh)(2)] (5) and [H3O][RuCl4(N equivalent to CMe)(2)] (7a) is discussed. Crystallization of 5 from CH2Cl2 gave trans-[RuCl2(N equivalent to CPh)(4)] (6). The solid-state structures of 3, 4a,b, 5, 6 and 7a are reported. Complex 4b forms a 3D network, while 6 displays a 2D structure, due to pi-interactions between the benzonitrile ligands. The (spectro)electrochemical behavior of 4a,b and 6 was studied at 25 and -72 degrees C and the results thereof are compared with [NEt4][RuCl4(N equivalent to CMe)(2)] (7b) and [RuCl(N equivalent to CPh)(5)][PF6] (8). The electrochemical response of the cation and the anion in 4a,b are independent from each other. [RuCl(N equivalent to CR)(5)](+) possesses one reversible Ru-II/Ru-III process. However, [RuCl4(N equivalent to CMe)(2)](-) was shown to be prone to ligand exchange and disproportionation upon formation of either a Ru-IV and Ru-II species at 25 degrees C, while at -72 degrees C the rapid conversion of the electrochemically formed species is hindered. In situ IR and UV/Vis/NIR studies confirmed the respective disproportionation reaction products of the aforementioned oxidation and reduction, respectively.

Identification of the C4 ‘-Oxidized Abasic Site as the Most Abundant 2-Deoxyribose Lesion in Radiation-Damaged DNA Using a Novel HPLC-Based Approach

A novel analytical high-performance liquid chromatography (HPLC)-based method of quantification of the yields of C4′-oxidized abasic sites, 1, in oxidatively damaged DNA has been elaborated. This new approach is based on efficient conversion of 1 into N-substituted 5-methylene-Delta(3)-pyrrolin-2-ones, 2, upon treatment of damaged DNA with primary amines in neutral or slightly acidic solutions with subsequent quantification of 2 by HPLC. The absolute and relative radiation-chemical yields of 1 in irradiated DNA solutions were re-evaluated using this method. The yields were compared with those of other 2-deoxyribose degradation products including 5-methylene-2(5H)-furanone, malondialdehyde, and furfural resulting from the C1′, C4′ and C5′-oxidations, respectively. The yield of free base release (FBR) determined in the same systems was employed as an internal measure of the total oxidative damage to the 2-deoxyribose moiety. Application of this technique identifies 1 as the most abundant sugar lesion in double-stranded (ds) DNA irradiated under air in solution (36% FBR). In single-stranded (ss) DNA this product is second by abundance (33% FBR) after 2-deoxyribonolactones (C1′-oxidation; 43% FBR). The production of nucleoside-5′-aldehydes (C5′-oxidation; 14% and 5% FBR in dsDNA and ssDNA, respectively) is in the third place. Taken together with the parallel reaction channel that converts C4′-radicals into malondialdehyde and 3′-phosphoglycolates, our results identify the C4’-oxidation as a prevalent pathway of oxidative damage to the sugar-phosphate backbone (50% or more of all 2-deoxyribose damages) in indirectly damaged DNA.

Elevated CO2 improves glucosinolate metabolism and stimulates anticancer and anti-inflammatory properties of broccoli sprouts

Sprouting process enhances plant bioactive compounds. Broccoli (Brassica oleracea L) sprouts are well known for their high levels of glucosinolates (GLs), amino acids, and antioxidants, which offer outstanding biological activities with positive impacts on plant metabolism. Elevated CO2 (eCO(2), 620 ppm) was applied for 9 days to further improve nutritive and health-promoting values of three cultivars of broccoli sprouts i.e., Southern star, Prominence and Monotop. eCO(2) improved sprouts growth and induced GLs accumulation e.g., glucoraphanin, possibly through amino acids production e.g., high methionine and tryptophan. There were increases in myrosinase activity, which stimulated GLs hydrolysis to yield health-promoting sulforaphane. Interestingly, low levels of ineffective sulforaphane nitrile were detected and positively correlated with reduced epithiospecifier protein after eCO(2) treatment. High glucoraphanin and sulforaphane levels in eCO(2) treated sprouts improved the anticarcinogenic and anti-inflammatory properties of their extracts. In conclusion, eCO(2) treatment enriches broccoli sprouts with health-promoting metabolites and bioactivities.

Effects of graphene surface functionalities towards controlled reinforcement of a lignin based renewable thermoplastic rubber

This report describes methods to enhance mechanical properties of a renewable thermoplastic rubber by incorporating functional graphene platelets into an equal-mass mixture of lignin, a feedstock from plant biomass, and a nitrile-butadiene rubber having 41 mol % acrylonitrile content (NBR41) that form a nanocomposite. Not all lignins yield mechanically strong material when they are combined with NBR41, and thus, limit its use for such rubbery products. Here, we evaluate different graphene oxides (GO) and reduced graphene oxides (rGO) dry-powders with different surface areas, functionality, and wettability in the synthesis of performance-enhanced nanocomposites of soft lignin/NBR41 matrix via a solvent-free, high shear reactive process. High surface area GO (HSGO) platelets with strong hydrophilicity exhibit good dispersion in the multiphase lignin/NBR41 composites with lignin dispersion varying from 200 to 2000 nm, resulting in superior reinforcement over other graphene derivatives. The addition of 1-4 wt % HSGO increased the tensile stress of the lignin/NBR41 thermoplastic rubber matrix by 60-160% (15-24 MPa) and the modulus by 200-700% (60-140 MPa). Scanning electron microscopy and small angle X-ray scattering results show that the well-dispersed HSGO platelets effectively disrupt the lignin-rich aggregates in NBR41 matrix, resulting in both strength and stiffness enhancements in the formed nanocomposites. This report on performance enhancement of lignin-based renewable polymers via the production of nanocomposite would increase potential for `finding the value of lignin’-a grand challenge associated with modern biorefineries.

Synthetic Route of 95-45-4, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 95-45-4.

A Catalytic Construction of Indoles via Formation of Ruthenium Vinylidene Species from N-Arylynamides

Treatment of ynamides with a catalytic amount of TpRuCl(PPh3)(2) resulted in the construction of indole scaffolds known as privileged structure motifs. This reaction involved a cascade of 1,2-rearrangement and cyclization carrying out C-C bond formation via a ruthenium vinylidene intermediate, as revealed by a deuterium-labeling experiments. Furthermore, the transformation of multi-functionalized ynamide, derived from a practical drug molecule, showed a high functional group tolerance of this reaction.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. In my other articles, you can also check out more blogs about 54663-78-4. Name: Tributyl(thiophen-2-yl)stannane.
