The Mtr Pathway of Shewanella oneidensis MR‐1 Couples Substrate Utilization to Current Production in Escherichia coli
Authors: TerAvest Michaela A. , Zajdel Tom J. , Ajo‐Franklin Caroline M. 
Published: August 2014

AbstractIntroducing an electronic interface into Escherichia coli will allow its enormous synthetic biology toolkit to be leveraged in bioelectrochemical applications. While E. coli expressing the Mtr pathway of Shewanella oneidensis MR‐1 transfer electrons to an anode, it has remained unclear if this current production alters the intracellular state of E. coli, which is a critical requirement for bioelectronic technologies. Here we address this by characterizing current production in Mtr‐expressing E. coli and its effects on cellular viability, substrate consumption, and product generation. We found that cymA‐mtr E. coli sustained ∼8‐fold higher current levels than a control strain. This increased current production did not change E. coli viability or substrate consumption, but it did alter metabolic fluxes. A shift to more oxidized products strongly suggests that the Mtr pathway improves redox balance in E. coli. By demonstrating the Mtr module couples current production to intracellular state, this work establishes Mtr‐expressing E. coli as a platform for accelerated development of bioelectronic technologies.

Published: August 2014

Abstract(Dibenzoylmethanato)boron difluoride derivatives containing triphenylamine moieties were synthesized as a new type of electron‐donor/π‐acceptor system. These new compounds exhibited long‐wavelength absorptions in the UV/Vis spectra, and reversible oxidation and reduction waves in cyclic voltammetry experiments. Their amphoteric redox properties are based on their resonance hybrid forms, in which a positive charge is delocalized on the triphenylamine moieties and a negative charge is localized on the boron atoms. Molecular orbital (MO) calculations indicate that their HOMO and LUMO energies vary with the number of phenylene rings connected to the difluoroboron‐chelating ring. This is useful for optimizing the HOMO and LUMO levels to an iodine redox (I−/I3−) potential and a titanium dioxide conduction band, respectively. Dye‐sensitized solar cells fabricated by using these compounds as dye sensitizers exhibited solar‐to‐electric power conversion efficiencies of 2.7–4.4 % under AM 1.5 solar light.
Rapid Assembly of Functionalised Spirocyclic Indolines by Palladium‐Catalysed Dearomatising Diallylation of Indoles with Allyl Acetate
Authors: Dhankher Persis , Benhamou Laure , Sheppard Tom D. 
Published: August 2014

AbstractHerein, we report the application of allyl acetate to the palladium‐catalysed dearomatising diallylation of indoles. The reaction can be carried out by using a readily available palladium catalyst at room temperature, and can be applied to a wide range of substituted indoles to provide access to the corresponding 3,3‐diallylindolinines. These compounds are versatile synthetic intermediates that readily undergo Ugi reactions or proline‐catalysed asymmetric Mannich reactions. Alternatively, acylation of the 3,3‐diallylindolinines with an acid chloride or a chloroformate, followed by treatment with aluminium chloride, enables 2,3‐diallylindoles to be prepared. By using ring‐closing metathesis, functionalised spirocyclic indoline scaffolds can be accessed from the Ugi products, and a dihydrocarbazole can be prepared from the corresponding 2,3‐diallylindole.
Alkali‐Metal Ion Catalysis and Inhibition in SNAr Displacement: Relative Stabilization of Ground State and Transition State Determines Catalysis and Inhibition in SNAr Reactivity
Authors: Um Ik‐Hwan , Cho Hyo‐Jin , Kim Min‐Young , Buncel Erwin 
Published: August 2014

AbstractWe report here the first observation of alkali‐metal ion catalysis and inhibition in SNAr reactions. The plot of kobsd versus [alkali‐metal ethoxide] exhibits downward curvature for the reactions of 1‐(4‐nitrophenoxy)‐2,4‐dinitrobenzene with EtOLi, EtONa, and EtOK, but upward curvature for the corresponding reaction with EtOK in the presence of 18‐crown‐6‐ether (18C6). Dissection of kobsd into the second‐order rate constants for the reactions with the dissociated EtO− and the ion‐paired EtOM (i.e., k and kEtOM, respectively) has revealed that the reactivity increases in the order EtOLi<EtONa<EtOK<EtO−<EtOK/18C6. This indicates that the reaction is inhibited by Li+, Na+, and K+ ions but is catalyzed by 18C6 K+ ion. The reactions of 1‐(Y‐substituted‐phenoxy)‐2,4‐dinitrobenzenes have been proposed to proceed through a stepwise mechanism, in which expulsion of the leaving group occurs after the rate‐determining step based on the kinetic result that σo constants exhibit a much better Hammett correlation than σ− constants. Alkali‐metal ion catalysis or inhibition has been discussed in terms of differential stabilization of ground‐state and transition‐state complexes through a qualitative energy profile. A π‐complexed transition‐state structure is proposed to account for the kinetic results.

AbstractThe synthesis, full characterization, photoreduction properties, and catalytic activity for the copper(I)‐catalyzed alkyne‐azide cycloaddition (CuAAC) reaction of a copper(II)–DMEDA (N,N′‐dimethylethylendiamine) complex is reported. Spectroscopic studies (UV/Vis, EPR) demonstrated that under daylight illumination highly effective copper(II) to copper(I) reduction occurs in this complex. These findings are in agreement with a high photoreduction quantum yield value of 0.22 in MeOH, and a value approaching unity as determined in THF. The reduction process, which can also be conducted by irradiation at 365 nm by using a standard TLC (thin layer chromatography) lamp, is ascribed to a highly efficient photoinduced electron transfer (PET) process mediated by the benzophenone photosensitizer present in the carboxylate counterion. Having deaerated the reaction mixture, the photogenerated copper(I) species proved to be highly active for the CuAAC reaction, demonstrated by reactions conducted with low catalyst loading (0.5 mol %) on a range of clickable protected and non‐protected mono‐ and disaccharides. Once initiated, the reaction can be stopped at any time on introducing air into the reaction medium. Deoxygenation followed by irradiation restores the activity, making the copper(II)–DMEDA complex a switchable catalyst of practical value.
