The development and exptl. validation of a computational protocol for optimizing a series of 3-hydroxy-pyran-4-one derivatives I [R = 2-(3-fluorophenyl)pyridinyl, 2-methyl-4-phenyl-1-imidazolyl, 1-phenyl-1H-pyrrolyl] as HIV integrase inhibitors (HIV INIs) was repoted. Starting from a previously developed micromolar inhibitors of HIV integrase (HIV IN), in-depth investigation based on an in silico structure-based combinatorial library designing approach was reported. This method combined a combinatorial library design and side chain hopping with Quantum Polarized Ligand Docking (QPLD) studies and mol. dynamics simulation. The resulting compounds I were assessed by the mentioned QPLD methodol. using a homol. model of full-length binary HIV IN/DNA for retrieving the best performing compounds acted as HIV INIs. Along with the prediction of physico-chem. properties, limited number of drug-like compounds were potentially displayed potent HIV IN inhibition. The compounds I were exptl. assessed in vitro for evaluating overall HIV-1 IN inhibition, HIV-1 IN strand transfer activity inhibition, HIV-1 activity inhibition and cellular toxicity. Gratifyingly, all of them showed relevant inhibitory activity in the in vitro tests along with no toxicity. Among them compound I [R = 2-(3-fluorophenyl)pyridinyl] represented the most promising compound as potential anti-HIV agent, showed inhibitory activity against HIV IN in the low nanomolar range comparable to that found for Raltegravir and relevant potency in inhibiting HIV-1 replication and HIV-1 IN strand transfer activity.

Independent generation of iminyl and pyrrol-1-yl radicals by flash vacuum pyrolysis of oxime ether I (X = N; R1 = MeO; R2 = 4-MeC6H4) and imine I (X = N; R1 = 4-MeC6H4; R2 = Me2N), resp., provided two regioisomeric pyrrolo[1,2-a]quinoxalines II. This shows that radical species interconvert via spirodienyl moiety at high temperatures Corresponding generation of pyrrol-1-yl radical from I (X = CH; R1 = 4-MeC6H4; R2 = Me2N) gave single pyrrolo[1,2-α]quinoline regioisomer as the only cyclized product. In this case, DFT calculations suggested that direct cyclization of pyrrol-1-yl took place, rather than formation of spirodienyl species and exclusive migration of C-N bond.

In 2022,EFSA Panel on Food Additives and Flavourings; Younes, Maged; Aquilina, Gabriele; Castle, Laurence; Engel, Karl-Heinz; Fowler, Paul J.; Frutos Fernandez, Maria Jose; Fuerst, Peter; Gundert-Remy, Ursula; Guertler, Rainer; Husoey, Trine; Manco, Melania; Moldeus, Peter; Passamonti, Sabina; Shah, Romina; Waalkens-Berendsen, Ine; Wolfle, Detlef; Wright, Matthew; Benigni, Romualdo; Bolognesi, Claudia; Cordelli, Eugenia; Chipman, Kevin; Degen, Gisela; Noerby, Karin; Svendsen, Camilla; Carfi, Maria; Martino, Carla; Tard, Alexandra; Vianello, Giorgia; Mennes, Wim published an article in EFSA Journal. The title of the article was 《Scientific opinion on Prosmoke BW 01》.Application In Synthesis of 2,5-Dimethoxytetrahydrofuran The author mentioned the following in the article:

The EFSA Panel on Food Additives and Flavorings (FAF) was requested to evaluate the safety of Prosmoke BW 01 as a new smoke flavoring primary product, in accordance with Regulation (EC) No 2065/2003. Prosmoke BW01 is produced by pyrolysis of beechwood (Fagus sylvatica L.) sawdust. Its water content is estimated at 56 wt%, the total identified volatile fraction accounts for 28 wt% of the primary product, corresponding to 64% of the solvent-free mass, while the unidentified fraction amounts to 16 wt% of the primary product. Anal. data provided for three batches demonstrated that their batch-to-batch-variability was sufficiently low. However, for the batch used for the toxicol. studies, there were substantial deviations in the concentration of nearly all the constituents compared to the other three batches. The dietary exposure of Prosmoke BW 01 was estimated to be between 6.2 and 9.2 mg/kg body weight (bw) per day, resp., using SMK-EPIC and SMK-TAMDI. Using the FAIM tool, the 95th percentile exposure estimates ranged from 3.2 mg/kg bw per day for the elderly to 17.9 mg/kg bw per day for children. The Panel noted that furan-2(5H)-one is present in all batches of the primary product at an average concentration of 0.88 wt%. This substance was evaluated by the FAF Panel as genotoxic in vivo after oral exposure. The Panel considered that the (geno)toxicity studies available on the whole mixture were not adequate to support the safety assessment, due to limitations in these studies and because they were performed with a batch which may not be representative for the material of commerce. Considering that the exposure estimates for furan-2(5H)-one are above the TTC value of 0.0025 μg/kg bw per day (or 0.15 μg/person per day) for DNA-reactive mutagens and/or carcinogens, the Panel concluded that Prosmoke BW 01 raises a concern with respect to genotoxicity. In the experiment, the researchers used many compounds, for example, 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Application In Synthesis of 2,5-Dimethoxytetrahydrofuran)

In 2022,Schafer, Michael; Stuenkel, Timo; Daniliuc, Constantin G.; Gilmour, Ryan published an article in Angewandte Chemie, International Edition. The title of the article was 《Regio- and Enantioselective Intermolecular Aminofluorination of Alkenes via Iodine(I)/Iodine(III) Catalysis》.Reference of 2,5-Dimethoxytetrahydrofuran The author mentioned the following in the article:

The regio- and enantio-selective, intermol. vicinal fluoroamination of α-trifluoromethyl styrenes was achieved by enantioselective II/IIII catalysis. Leveraging C2-sym. resorcinol-based aryl iodide catalysts, it was possible to intercept the transient iodonium intermediate using simple nitriles, which function as both the solvent and nucleophile. In situ Ritter reaction provides direct access to the corresponding amides (up to 89% yield, e.r. 93 : 7). This main group catalysis paradigm inverts the intrinsic regioselectivity of the uncatalyzed process, thereby providing facile access to tertiary, benzylic stereocenters bearing both CF3 and F groups. Privileged phenethylamine pharmacophores was generated in which there is complete local partial charge inversion (CF3δ-/Fδ- vs. CH3δ+/Hδ+). Crystallog. analyses of representative β-fluoroamide products reveal highly pre-organized conformations that manifest the stereoelectronic gauche effect.

Pyrrolylanilines such as I, pyrrolylbenzylamines, and arylethylamines underwent chemoselective tandem condensation and cyclocondensation reactions with carboxylic acids such as RCO2H mediated by di-Et bromomalonate or di-Et bromo(methyl)malonate and phenylsilane or diphenylsilane in the presence of a hexamethylphosphetane oxide to yield pyrroloquinoxaline such as II [R = MeOCH2, n-Pr, H2C:CHCH2CH2, Ph, 2-MeC6H4, 3-MeC6H4, 4-ClC6H4, 4-FC6H4, 4-MeOC6H4, PhCH2SCH2, TsNHCH2, Br(CH2)5, 3-chloro-1-cyclobutyl], pyrrolobenzodiazepines, a dihydro-β-carboline, and dihydroisoquinolines. The method was also used for Bischler-Napieralski cyclocondensations of aralkyl amides. A bromophosphonium bromide was generated as the key intermediate. A PIII/PV redox catalyst enabled iterative redox-neutral transformations complementary to reactions using the reductive driving force of the PIII/PV couple.

《Pseudo-5-Fold-Symmetrical Ligand Drives Geometric Frustration in Porous Metal-Organic and Hydrogen-Bonded Frameworks》 was written by Haase, Frederik; Craig, Gavin A.; Bonneau, Mickaele; Sugimoto, Kunihisa; Furukawa, Shuhei. Electric Literature of C6H12O3 And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

Reticular framework materials thrive on designability, but unexpected reaction outcomes are crucial in exploring new structures and functionalities. By combining “”incompatible”” building blocks, we employed geometric frustration in reticular materials leading to emergent structural features. The combination of a pseudo-C5-sym. organic building unit based on a pyrrole core with a C4-sym. copper paddlewheel synthon led to three distinct frameworks by tuning the synthetic conditions. The frameworks show structural features typical for geometric frustration: self-limiting assembly, internally stressed equilibrium structures, and topol. defects in the equilibrium structure, which manifested in formation of a hydrogen-bonded framework, distorted and broken secondary building units, and dangling functional groups, resp. The influence of geometric frustration on the CO2 sorption behavior and the discovery of a new secondary building unit shows geometric frustration can serve as a strategy to obtain highly complex porous frameworks.2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Electric Literature of C6H12O3) was used in this study.

We report the synthesis of π-extended ullazine derivatives annulated with either electron-poor pyridine or electron-rich thiophene units through a metal-free, photochem. cyclodehydrochlorination (CDHC) reaction. The strongest electron-donor derivative, 7-tetradecylthieno[3′,2′:7,8]indolizino[6,5,4,3-ija]thieno[2,3-c]quinolone, was copolymerized with electron-deficient thienopyrroledione (TPD), isoindigo (IID), and diketopyrrolopyrrole (DPP) derivatives to provide three donor-acceptor conjugated polymers (D-A CPs). Their photophys., electrochem. and photovoltaic (PV) properties were investigated. The polymers showed broad UV-vis-NIR absorption bands with λmax values of 612 nm, 698 nm, 788 nm in chloroform and exhibited optical bandgap (Eoptg) of 1.58 eV, 1.41 eV, 1.24 eV measured as films. Inverted bulk heterojunction polymer solar cells (BHJ-PSCs) were fabricated using these polymers as host and light-harvesting materials. The device based on P3:PC70BM blends shows the best power conversion efficiency (PCE) of 2.23% (Voc = 0.55 V, Jsc = 7.86 mA cm-2, FF = 52%). These promising results demonstrate that π-extended ullazine derivatives can be used as electron-rich building blocks for the construction of D-A CPs for efficient PSCs applications.
