In the present examination, the thermochemical behavior of the lignin extracted from willow (Salix matsudana cv. Zhuliu) by deep eutectic solvents (DES) treatment (DES-lignin) with varied times were investigated with the techniques of thermogravimetric analyzer, in situ diffuse reflectance infrared pyrolysis (in situ-FTIR), and pyrolysis-gas chromatography/mass spectrometry. The results showed that thermal degradation of DES-lignin mainly occurred at 185-470 degrees C with two maximum weight loss peaks at 265 degrees C and 380 degrees C respectively, and the solid residue was 40% when terminated at 800 degrees C. The identified cluster of aromatics from in situ-FTIR was detected earlier and stronger than those of small molecular gases, suggesting cleavage of lignin intermolecular linkages dominated the initial pyrolysis process. The DES-lignin was sensitive to pyrolysis to produce aromatics. The total phenols yield from DES-lignin pyrolysis reached a maxima of 95.1% at 450 degrees C, among which phenol and guaiacol accounted for the largest proportion, i.e. 20.8% and 24.2% respectively. In addition, product distribution was remarkably affected by pyrolysis temperature and the DES treatment time used for lignin isolation.

Name: 2,5-Dimethoxybenzaldehyde. I found the field of Chemistry very interesting. Saw the article Chemoselective Cross-Coupling between Two Different and Unactivated C(aryl)-O Bonds Enabled by Chromium Catalysis published in 2020.0, Reprint Addresses Zeng, XM (corresponding author), Sichuan Univ, Coll Chem, Key Lab Green Chem & Technol, Minist Educ, Chengdu 610064, Peoples R China..

We report here the first example of cross-coupling between two different and unactivated C(aryl)-O bonds with chromium catalysis. The combination of a low-cost Cr(II) salt, 4,4′-di-tart-butyl-2,2′-dipyridyl (dtbpy) as the ligand, and magnesium as the reductant shows high reactivity in promoting the reductive cross-coupling of aryl methyl ether derivatives with aryl esters by cleavage and coupling of two different C(aryl)-O bonds under mild conditions. The formation of active low-valent Cr species by reduction of CrCl2 with Mg can be considered, which prefers to initially activate the C(aryl)-O bond of phenyl methyl ether with the chelation help of dtbpy and an o-imine auxiliary. The subsequent consecutive reduction, second C(aryl)-O activation, and reductive elimination allow for the achievement of selective cross-coupling of C(aryl)-O/C(aryl)-O bonds.

Rationale The halogenated derivatives of N-(2-methoxy)benzyl-2,5-dimethoxyphenethylamine (25-NBOMe) such as the 4-bromo analogue (25B-NBOMe) represent a new class of hallucinogenic or psychedelic drugs. The purpose of this study was to determine the role of the electron-donating groups (halogen and dimethoxy) in the pathway of decomposition for the distonic molecular radical cation in the electron ionization mass spectrometry (EI-MS) process of the trifluoroacetamide (TFA) derivatives. Methods The systematic removal of substituents from the 4-halogenated 2,5-dimethoxyphenethylamine portion of the N-dimethoxybenzyl NBOMe analogues allowed an evaluation of structural effects on the formation of major fragment ions in the EI-MS of the TFA derivatives. All six regioisomeric dimethoxybenzyl-substituted analogues (2,3-, 2,4-, 2,5-, 2,6-, 3,4- and 3,5-dimethoxy) for the four series of phenethyl aromatic ring substitution patterns were prepared, derivatized and analyzed via gas chromatography coupled with EI-MS. Results The analogues yield two unique radical cation fragments from the decomposition of the common distonic molecular radical cation. The substituted phenylethene radical cation (m/z 164) is the base peak or second most abundant ion in all six TFA-2,5-dimethoxyphenethylamine isomers. The dimethoxybenzyltrifloroacetamide radical cation (m/z 263) is the base peak or second most abundant ion in the 2- and 3-monomethoxyphenethylamine isomers. However, the 2- and 3-methoxyphenylethene radical cation (m/z 134) is among the five most abundant ions for each of these twelve isomers. Only one isomer in the phenethylamine series yields the corresponding unsubstituted phenylethene radical cation at m/z 104. Conclusions The decomposition of the hydrogen-rearranged distonic molecular radical cation favors formation of the dimethoxybenzyltrifloroacetamide (m/z 263) species for the less electron-rich phenethyl aromatic rings. The addition of electron-donating groups to the aromatic ring of the phenethyl group as in the NBOMe-type molecules shifts the decomposition of the common distonic molecular radical cation to favor the formation of the electron-rich substituted phenylethene radical cation.

We report a novel ecofriendly cascade reaction for the synthesis of arylsulfonyl-4H-pyran derivatives by a three component fusion reaction of chosen aldehyde, dimedone and phenylsulphonyl acetonitrile at room temperature using ruthenia doped fluorapatite (RuO2/FAp) as recyclable catalyst. Different percentages of RuO2/FAp materials were prepared and characterized by FT-IR, P-XRD, BET, SEM-EDX and TEM analysis. Attractive features of the synthetic approach are operational simplicity, cost-effectiveness, short reaction time and excellent yields. Easily recoverable and reusable catalyst material without any deceptive loss of catalytic activity up to seven cycles is additional benefit.

A new series of 2,4-disubstituted-2-thiopyrimidines 6a-t, 9a, and 9b was efficiently designed and synthesized as antiangiogenic and cytotoxic agents. Compounds 6j, 6l, and 6d showed IC50 values of 1.23, 3.78, and 3.84 mu M, respectively, against the vascular endothelial growth factor receptor-2 (VEGFR-2). Most of the synthesized 2-thiouracils showed antiproliferative activity against the HepG2 cell line (hepatocellular carcinoma) in the micromolar range, for instance, 9b, 6l, 6m, 6n, and 6j displayed IC50 = 7.92, 8.35, 8.51, 9.59, and 13.06 mu M, respectively, relative to sorafenib (III; IC50 = 10.99 mu M). Also, compounds 6j, 9a, 6m, and 6s (IC50 = 15.21, 16.96, 17.68, and 18.15 mu M, respectively) are the most potent compounds against the UO-31 cell line. Further evaluation of the effect of the synthesized candidates on VEGFR-2 in the HepG2 cell line demonstrated that compounds 6j and 6l exhibit VEGFR-2 inhibitory activity of 87% and 84%, respectively, relative to sorafenib (III; 92%). In silico docking of the synthesized hits into the binding site of VEGFR-2 showed their ability to perform the main binding interactions with the key amino acids in the binding site. Studying the in silico predicted ADME (absorption, distribution, metabolism, and excretion) parameters for the synthesized thiouracils demonstrated that they have favorable pharmacokinetic and drug-likeness properties. These results demonstrate that the 2,4-disubstituted thiouracils 6 and 9 have not only favorable antiangiogenic and antiproliferative activity but also satisfy the criteria required for the development of orally bioavailable drugs. Consequently, they represent a biologically active scaffold that should be further optimized for future discovery of potential hits.

Stable phenoxyl radicals H-bonded to phenols were successfully isolated. The effect of the intermolecular Hbonding to the concerted proton coupled electron transfer (CPET) reactions of the aldimines and the stability and spin distribution of the H-bonded phenoxyls are reported. Salts of iminium-phenol derivatives as cations and the corresponding imine-phenolato derivatives coordinated to zinc(II) as anions, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+), were isolated, where ArOH are aldimine derivatives. Notably, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts undergo CPET reactions in air affording phenoxyl analogues, [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN. [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts incorporate intermolecular iminium-phenolato, [(Zn)Ar-O–+HN=CH-] H-bonds, while [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN moieties contain intermolecular phenoxyl-phenol, [Ar-O-HO-Ar](center dot), H-bonds. The phenoxyls are presented in two forms, [(Zn)Ar-O-center dot—HO-Ar (zinc phenoxyl) <-> (Zn)Ar-OH—O-center dot-Ar (free phenoxyl)]. In crystals, the spin density scatters on both phenolic fragments corresponding to a delocalized state, while in solution the latter form has been calculated as a ground electronic state. The X-band EPR spectra of crystals, solutions and frozen glasses were analyzed. The powder spectra at g = 2.0030 +/- 0.0005 and the frozen glass spectra at g = 2.0075 +/- 0.0003 follow the hyperfine patterns due to N-14 (I = 1) nuclei. In fluid solutions, the g values of the hyperfine signals due to (14) N and H-1 nuclei are 2.0078 +/- 0.0001. 1-3 exhibit absorption bands at 350-390 nm due to pi ->pi* intraligand charge transfer (ILCT) transitions, while the radical species, in addition to pi ->pi transitions at 405-440 nm, display phenol to phenoxyl intervalence charge transfer (WCT) transitions at 600-650 nm. The cyclic voltammograms (CVs) of 1-3 depend on the scan rates; at lower scan rates (100-400 mV/s) the CPET reactions occur at -0.92 to -0.96 V versus Fc(+)/Fc couple, whereas at higher scan rates (1000-2400 mV/s), the oxidation occurs by the electron transfer (ET) path at 0.05-0.12 V. Thus, a potential shift of similar to 1.0 V is recorded due to CPET reactions facilitated by H-bonding.

An expedient and eco-friendly synthesis of 1-aryl/heteroaryl-[1,2,4]-triazolo[4,3-a]quinoxalin-4(5H)-ones (4) has been accomplished via iodobenzene diacetate mediated oxidative intramolecular cyclization of 3-(2-(aryl/heteroarylidene)hydrazinyl)-quinoxalin-2(1H)-ones (3). Ten synthesized compounds 3 and 4 (10-40 mu g) on irradiation with UV light at lambda(max) 312 nm could lead to cleavage of supercoiled pMaxGFP DNA (Form I) into the relaxed DNA (Form II) without any additive. Further, DNA cleaving ability of triazoles was quantitatively evaluated and was found to be dependent on its structure, concentration, and strictly on photoirradiation time. Mechanistic investigations using several additives as potential inhibitors/activator revealed that the DNA photocleavage reaction involves Type-I pathway leading to formation of superoxide anion radicals (O-2(-center dot)) as the major reactive oxygen species responsible for photocleavage process.
