Ross, Sean P.;Rahman, Ajara A.;Sigman, Matthew S. research published 《 Development and Mechanistic Interrogation of Interrupted Chain-Walking in the Enantioselective Relay Heck Reaction》, the research content is summarized as follows. The formation of alkyl-palladium complexes via the nucleopalladation of alkenes is the entry point for a wide range of diverse reactions. One possibility is that the intermediate alkyl-Pd complexes can undergo a “chain-walking” event, to allow for remote functionalization through various termination processes. However, there are few methods to selectively interrupt the chain-walking process at a prescribed location. Herein, we demonstrate that a variety of homoallylic protected amines undergo an interrupted enantioselective relay Heck reaction to give enantioenriched allylic amine products. The selectivity of this process can be diverted to exclusively yield the ene-amide products by virtue of changing the nature of the amine protecting group. To rationalize this observation, we combine experiment and computation to investigate the mechanism of the chain-walking process and termination events. Isotopic labeling experiments and the computed reaction pathways suggest that the system is likely under thermodn. control, with the selectivity being driven by the relative stability of intermediates encountered during chain-walking. These results illustrate that the chain-walking of alkyl-palladium complexes can be controlled through the alteration of thermodn. processes and provides a roadmap for exploiting these processes in future reaction development.

Rymaruk, Matthew J.;O’Brien, Cate T.;Gyoergy, Csilla;Darmau, Bastien;Jennings, James;Mykhaylyk, Oleksandr O.;Armes, Steven P. research published 《 Small-Angle X-Ray Scattering Studies of Block Copolymer Nano-Objects: Formation of Ordered Phases in Concentrated Solution During Polymerization-Induced Self-Assembly》, the research content is summarized as follows. We report that polymerization-induced self-assembly (PISA) can be used to prepare lyotropic phases comprising diblock copolymer nano-objects in non-polar media. RAFT dispersion polymerization of benzyl methacrylate (BzMA) at 90°C using a trithiocarbonate-capped hydrogenated polybutadiene (PhBD) steric stabilizer block in n-dodecane produces either spheres or worms that exhibit long-range order at 40% weight/weight solids. NMR studies enable calculation of instantaneous copolymer compositions for each phase during the BzMA polymerization As the PBzMA chains grow longer when targeting PhBD₈₀-PBzMA₄₀, time-resolved small-angle X-ray scattering reveals intermediate body-centered cubic (BCC) and hexagonally close-packed (HCP) sphere phases prior to formation of a final hexagonal cylinder phase (HEX). The HEX phase is lost on serial dilution and the aligned cylinders eventually form disordered flexible worms. The HEX phase undergoes an order-disorder transition on heating to 150°C and a pure HCP phase forms on cooling to 20°C.

Saborio, Maricruz G.;Privat, Karen;Tran, Bich Ngoc;Zetterlund, Per B.;Agarwal, Vipul;Estrany, Francesc research published 《 Polymer/Reduced Graphene Oxide/Lignosulfonate Nanocomposite Films as Pseudocapacitor Cathodes》, the research content is summarized as follows. Robust and electrochem. stable electrodes are critical for emerging energy storage devices. In this work, we describe the synthesis and characterization of an asym. pseudocapacitor with a P(nBA-stat-BzMA)/reduced graphene oxide (rGO, 5 wt %) nanocomposite cathode incorporating a low content of lignosulfonate (LS, 5 wt %) and a P(nBA-stat-BzMA)/rGO anode. Besides the advantageous green source and low cost of LS, its properties as a binder and its redox groups contribute to the electrochem. performance improvement of the pseudocapacitor. First, the electrochem. optimization and characterization of an asym. unit cell is performed. Subsequently, a series of 10 unit cells are arranged in a “stack of cells”; electrochem. tests show this assembly to have a capacitance of 4.90 F cm^-3 (8.60 F g^-1), maximum power of 610 W kg^-1, energy of 4.32 W h kg^-1, loss of electroactivity of 1.8%, capacitance retention of 98%, and Coulombic efficiency of 108% after 1000 charge-discharge cycles at a constant current of 0.12 A cm^-3. Morphol. anal. revealed an increase in surface roughness after LS incorporation within the cathode. Electrode-electrolyte resistances were calculated via electrochem. impedance spectroscopy, which allowed us to propose a model of electrode-electrolyte interaction for this system.

We report here a practical methodol. to obtain these compounds Using the copper-catalyzed Chan-Lam coupling, we synthesized new N-arylcytisine derivatives at room temperature, in air and using inexpensive phenylboronic acids. Cytisine and 3,5-dihalocytisines can act as substrates, and among the products, the p-Br-derivative was used as a substrate to obtain biaryl derivatives under Pd-coupling conditions; ester-derivative was converted into its acid and amide derivatives using classical carbodiimide conditions.

Seitzinger, Claire L.;Hall, Cecilia C.;Lodge, Timothy P. research published 《 Photoreversible Order-Disorder Transitions in Block Copolymer/Ionic Liquid Solutions》, the research content is summarized as follows. External stimuli are of interest in controlling the nanoscale morphol. in self-assembling polymer materials. While temperature is commonly used to control the state of microphase separation in block polymer solutions, light is a highly tunable, contactless method that can be spatially selective. Here, we use UV irradiation to induce order-disorder transitions (ODTs) in concentrated solutions of four poly(Me methacrylate)-b-poly(benzyl methacrylate-s-4-phenylazophenyl methacrylate) block copolymers in three imidazolium-based ionic liquids Due to a significant change in polarity in the phenylazophenyl methacrylate monomer upon UV irradiation, a bistable temperature window exists between the ODT in the dark and under UV irradiation, allowing for light-triggered ODTs. UV-irradiated small-amplitude oscillatory shear rheol. is used to locate the bistable window and then to trigger ODTs reversibly with light. The ordered states formed in the dark are determined by small-angle X-ray scattering. Three tunable factors are explored within the system: the relative lengths of the copolymer blocks, the selectivity of the solvent, and the content of the photoactive monomer. The block composition was found to mainly influence the ordered state formed by the system after microphase separation The selectivity of the solvent is the most promising method for tuning the ODT temperature, and the amount of photoactive monomer controls the width of the bistable window.

G. research published 《 De novo design of type II topoisomerase inhibitors as potential antimicrobial agents targeting a novel binding region》, the research content is summarized as follows. By 2050, it is predicted that antimicrobial resistance will be responsible for 10 million global deaths annually, more deaths than cancer, costing the world economy $100 trillion. Clearly, strategies to address this problem are essential as bacterial evolution is rendering our current antibiotics ineffective. The discovery of an allosteric binding site on the established antibacterial target DNA gyrase offers a new medicinal chem. strategy. As this site is distinct from the fluoroquinolone binding site, resistance is not yet documented. Using in silico mol. design methods, we have designed and synthesized a novel series of biphenyl-based inhibitors inspired by a published thiophene-based allosteric inhibitor. This series was evaluated in vitro against Escherichia coli DNA gyrase and E. coli topoisomerase IV with the most potent compounds exhibiting IC₅₀ values towards the low micromolar range for DNA gyrase and only ∼2-fold less active against topoisomerase IV. The structure-activity relationships reported herein suggest insights to further exploit this allosteric site, offering a pathway to overcome developing fluoroquinolone resistance.
