Jeon, Hongjun;Choi, Sang Won;Park, Soojun;Lee, Seokwoo;Kim, Sanghee research published ã€?Synthesis of Bridged Oxabicycles via Cascade Reactions involving O-Acyloxocarbenium Ion Intermediatesã€? the research content is summarized as follows. Compared to related electrophilic species, O-acyloxocarbenium ions (AOIs) have been much less utilized in organic synthesis due to the lack of an efficient formation method.

Based on the authors’ AOI system with a pendant nucleophile, a unique bridged bicyclic system was obtained via an epoxonium-like transition state. The proposed mechanism is based on exptl. and computational studies.

Jeon, Jong Yeob;Park, Sungmin;Han, Junyoung;Maurya, Sandip;Mohanty, Angela D.;Tian, Ding;Saikia, Nayan;Hickner, Michael A.;Ryu, Chang Y.;Tuckerman, Mark E.;Paddison, Stephen J.;Kim, Yu Seung;Bae, Chulsung research published ã€?Synthesis of Aromatic Anion Exchange Membranes by Friedel-Crafts Bromoalkylation and Cross-Linking of Polystyrene Block Copolymersã€? the research content is summarized as follows. Elastomeric anion exchange membranes (AEMs) were prepared by acid-catalyzed Friedel-Crafts alkylation of the polystyrene block of polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS) using bromoalkylated tertiary alcs. and triflic acid as a catalyst, followed by amination with trimethylamine. This simple one-step bromoalkylation allowed convenient control of both the degree of functionalization and cation tether length by changing the molar ratio and the structure of the bromoalkylated tertiary alc. The resulting quaternary ammonium-functionalized ionic triblock SEBS copolymers showed a microphase-separated morphol. on the 35 nm length scale. A series of AEMs with different ion exchange capacities and ion tether lengths were systematically investigated by comparing swelling and anion conductivity Because the SEBS AEMs showed high swelling and low dimensional stability in water due to the rubbery nature of SEBS, the hard segment PS units were crosslinked by 1,6-hexanediamine for practical use. The crosslinking of SEBS AEMs reduced water uptake significantly (e.g., 155% vs. 28%) and enhanced their mech. properties. Because the backbone of the SEBS AEMs are composed of all carbon-carbon bonds, they showed good alk. stability, preserving their IEC and OH^– conductivity after testing in a 1 M NaOH solution at 80 °C for 500 h. Alk. membrane fuel cell performance was evaluated with the crosslinked SEBS AEM, and a peak power d. of 520 mW/cm² was achieved at 60 °C under H₂/O₂ conditions.

Huan, Leitao;Shu, Xiaomin;Zu, Weisai;Zhong, De;Huo, Haohua research published ã€?Asymmetric benzylic C(sp³)-H acylation via dual nickel and photoredox catalysisã€? the research content is summarized as follows. An asym. benzylic C-H acylation of alkylarenes employing carboxylic acids as acyl surrogates for synthesis of α-aryl ketones I [R¹ = Me, 2-thienyl, 2-naphthyl, etc.; R² = Me, Et, CH₂CH₂OAc, etc.; Ar = 3-thienyl, 4-FC₆H₄, 1,1′-biphenyl, etc.] via nickel and photoredox dual catalysis was reported.

The utility of this method was showcased in gram-scale synthesis and late-stage modification of medicinally relevant mols. Mechanistic studies suggested a photocatalytically generated bromine radical could perform benzylic C-H cleavage to activate alkylarenes as nucleophilic coupling partners which could then engage in a nickel-catalyzed asym. acyl cross-coupling reaction. This bromine-radical-mediated C-H activation strategy could be also applied to enantioselective coupling of alkylarenes with chloroformate for synthesis of chiral α-aryl esters, e.g., II.

Huang, Jingsheng;Huang, Jiaguo;Cheng, Penghui;Jiang, Yuyan;Pu, Kanyi research published ã€?Near-Infrared Chemiluminescent Reporters for In Vivo Imaging of Reactive Oxygen and Nitrogen Species in Kidneysã€? the research content is summarized as follows. Despite the superior sensitivity of chemiluminescence over fluorescence, most chemiluminescence reporters only emit visible light, and have low water solubility, making them poorly equipped for in vivo imaging applications. Herein two near-IR (NIR) chemiluminescent reporters (NCRs) with high renal clearance for real-time imaging of reactive oxygen and nitrogen species in the kidneys were synthesized. NCRs comprise a β-cyclodextrin unit and a modified dicyanomethylene-4H-pyran containing Schaap′s dioxetane as the renal-clearance enabler and the chemiluminescent moiety, resp. NCR1 and NCR2 specifically activate their NIR chemiluminescence towards superoxide anion (O₂^â€?) and peroxynitrite (ONOO^–), resp. By virtue of their nanomolar sensitivity and high renal clearance, NCRs not only detect subtle upregulation of endogenous RONS in cells but also enable noninvasive monitoring of RONS in the kidneys under nephrotoxic exposure. The earlier activation of NCR1 relative to NCR2 implies the sequential upregulation of O₂^â€? and ONOO^– during drug-induced acute kidney injury (AKI). Moreover, detection of the fluorescence of excreted NCRs permits urinalysis of AKI, detecting the upregulation of RONS at least 24 h earlier than histol. anal. Thus, this study not only introduces ultrasensitive NIR chemiluminescent probes but also provides guidelines to transform them into legitimate imaging agents for organ-specific in vivo detection.

The iron and nickel bimetallic nanoparticles supported by the block copolymer polystyrene-block-poly (acrylic acid) (PS-b-PAA-nZVI-Ni) were synthesized successfully and were applied to assess the degradation of 1,1,1-trichloroethane (1,1,1-TCA) in water. An optimal dose of Ni loading was 2 wt%, while an optimal mass ratio of PS-b-PAA to Ni/Fe, i.e., 0.5:1, at which the dechlorination efficiency was a maximum The size of PS-b-PAA-nZVI-Ni nanoparticles (average size �50 nm) was three times smaller than that of nZVI-Ni due to the prevention of agglomeration of the resultant zerovalent iron nanoparticles by PS-b-PAA. In the applying aspect, the pseudo-first-order rate constant (Kobs) of 1,1,1-TCA removal by PS-b-PAA-nZVI-Ni was 0.0142 min-1 within 240 min, which was approx. five times higher than nZVI.

Metal hydride complexes are key intermediates for N-alkylation of amines with alcs. by the borrowing hydrogen/hydrogen autotransfer (BH/HA) strategy. Reactivity tuning of metal hydride complexes could adjust the dehydrogenation of alcs. and the hydrogenation of imines. Herein we report ruthenium(II) complexes with hetero-bidentate N-heterocyclic carbene (NHC)-phosphine ligands, which realize smart pathway selection in the N-alkylated reaction via reactivity tuning of [Ru-H] species by hetero-bidentate ligands. In particular, complex I·BArF^– with a Ph wingtip group and BArF^– counter anion, is shown to be one of the most efficient pre-catalysts for this transformation (temperature is as low as 70°C, neat conditions and catalyst loading is as low as 0.25 mol%). A large variety of (hetero)aromatic amines and primary alcs. were efficiently converted into mono-N-alkylated amines in good to excellent isolated yields. Notably, aliphatic amines, challenging methanol and diamines could also be transformed into the desired products. Detailed control experiments and d. functional theory (DFT) calculations provide insights to understand the mechanism and the smart pathway selection via [Ru-H] species in this process.

Insect pests seriously decrease the yield and quality of agricultural crops. Resistance to commonly used insecticides is increasingly undermining their effectiveness, and therefore the development of agents with novel modes of action is desirable. Isoxazolines are a new class of insecticides that act on γ-aminobutyric acid (GABA) gated chloride channels. In this work, we used the highly active 4-triazolyphenyl isoxazoline DP-9 as a parent structure to design and synthesize a series of quaternary ammonium salt (QAS) derivatives, and we systematically evaluated their insecticidal and antifungal activities. RESULTS : Many of the synthesized QASs exhibit insecticidal activities equivalent to or higher than that of DP-9. In particular, compounds I-31 (93%, 0.00005 mg/L) and I-34 (80%, 0.00001 mg/L) showed insecticidal activities against diamondback moth larvae that were 2-10 times higher than those of fluralaner (70%, 0.0001 mg/L) and DP-9 (80%, 0.0001 mg/L), in addition to showing excellent activities against oriental armyworm, fall armyworm, cotton bollworm, corn borer, and mosquito larvae. Furthermore, all of the synthesized compounds also showed broad-spectrum fungicidal activities. The insecticidal activities of QAS derivatives of DP-9 were the same as or better than the activity of DP-9. Compounds I-31 and I-34 showed better insecticidal activities against diamondback moth larvae than fluralaner and DP-9, and thus are promising new candidates for insecticide research.
