Verma, Suryadev K.;Punji, Benudhar research published 《 Manganese-Catalyzed C(sp²)-H Alkylation of Indolines and Arenes with Unactivated Alkyl Bromides》, the research content is summarized as follows. Selective C(sp²)-H bond alkylation of indoline like 2,3-dihydro-1-(2-pyridinyl)-1H-indole, carbazole like 9-(2-pyridinyl)-9H-carbazole and (2-pyridinyl)arenes I (R¹ = H, 4-Me, 4-OMe, 3-F₃C) with unactivated alkyl bromides R²(CH₂)₂Br (R² = Et, Pr, 4-(9H-carbazol-9-yl)butyl, etc.) is achieved using MnBr₂ catalyst in the absence of an external ligand. The alkylation uses a simple LiHMDS base and avoids the necessity of Grignard reagent, unlike other Mn-catalyzed C-H functionalization. This reaction proceeded either through a five- or less-favored six-membered metallacycle, and tolerated diverse functionalities, including alkenyl, alkynyl, silyl, aryl ether, pyrrolyl, indolyl, carbazolyl and alkyl bearing fatty alc. and polycyclic-steroid moieties. Alkylation follows a single electron transfer (SET) pathway involving 1e oxidative addition of alkyl bromide and rate-limiting C-H metalation.

Tomasic, Tihomir;Rabbani, Said;Jakob, Roman P.;Reisner, Andreas;Jakopin, Ziga;Maier, Timm;Ernst, Beat;Anderluh, Marko research published 《 Does targeting Arg98 of FimH lead to high affinity antagonists?》, the research content is summarized as follows. Bacterial resistance has become an important challenge in the treatment of urinary tract infections. The underlying resistance mechanisms can most likely be circumvented with an antiadhesive approach, antagonizing the lectin FimH located at the tip of fimbriae of uropathogenic E. coli. Here we report on a novel series of FimH antagonists based on the 1-(α-D-mannopyranosyl)-4-phenyl-1,2,3-triazole scaffold, designed to incorporate carboxylic acid or ester functions to interact with FimH Arg98. The most potent representative of the series, ester I, displayed a K_d value of 7.6 nM for the lectin domain of FimH with a general conclusion that all esters outperform carboxylates in terms of affinity. Surprisingly, all compounds from this new series exhibited improved binding affinities also for the R98A mutant, indicating another possible interaction contributing to binding. Our study on 1-(α-D-mannopyranosyl)-4-phenyl-1,2,3-triazole-based FimH antagonists offers proof that targeting Arg98 side chain by a “chem. common sense”, i.e. by introduction of the acidic moiety to form ionic bond with Arg98 is most likely unsuitable approach to boost FimH antagonists’ potency.

Tomer, Sanjiv O.;Soni, Hemant P. research published 《 Cinchona alkaloid derivative modified Fe₃O₄ nanoparticles for enantioselective ring opening of meso-cyclic anhydrides》, the research content is summarized as follows. In the present work, the mol. framework of quinidine was modified at the methoxy functional group of the C6′ carbon of the quinoline moiety with a long-chain carboxylic acid group (-COOH) and it was used as a capping agent during the synthesis of Fe₃O₄ NPs. The resulting modified quinidine capped Fe₃O₄ (Fe₃O₄@mQD) NPs were characterized by different techniques and used for enantioselective ring opening (ERO) by methanolysis in a heterogeneous mode of catalysis. The interactions of mQD with the Fe₃O₄ surface, as well as its % loading, were studied using FTIR spectroscopy and thermal anal. techniques. Reaction parameters like the solvent system, temperature, and substrate were optimized. ERO of succinic and glutaric anhydrides by methanolysis was carried out in the presence of Fe₃O₄@mQD NPs. The optimized protocol can produce a chiral hemiester with high enantioselectivity (up to 98% ee) and excellent % yield (more than 90% in most of the cases).

A poly(methacrylate) with benzocyclobutene side chains, CL, has been synthesized by radical polymerization for use as a crosslinking additive for a previously reported benzocyclobutene-functionalized fullerene, PCBCB, which can be thermally insolubilized following solution processing. Films of PCBCB incorporating CL and n-doped with (IrCp*Cp)₂ exhibit in-plane elec. conductivities around ten times higher than those of n-doped films without CL, while the use of CL also reduces leaching of dopant ions from the film upon washing. The performance and stability of perovskite solar cells using insolubilized PCBCB:CL, insolubilized PCBCB, or PCBM as top electron-extraction layers are compared; cells with undoped PCBCB:CL extraction layers exhibit higher average and maximum power conversion efficiencies (16 and 18.5%, resp.) than their PCBM and PCBCB counterparts.

Trinklein, Timothy J.;Warren, Cable G.;Synovec, Robert E. research published 《 Determination of the signal-to-noise ratio enhancement in comprehensive three-dimensional gas chromatography》, the research content is summarized as follows. We investigate the extent to which comprehensive three-dimensional gas chromatog. (GC³) provides a signal enhancement (SE) and a signal-to-noise ratio enhancement (S/N_Rel) relative to one-dimensional (1D)-GC. Specifically, the SE is defined as the ratio of the tallest ³D peak height from the GC³ separation to the 1D peak height from the unmodulated 1D-GC separation A model is proposed which allows the analyst to predict the theor. attainable SE (SE_T) based upon the peak width and sampling d. inputs. The model is validated via comparison of the SE_T to the exptl. measured SE (SE_M) obtained using total-transfer GC³ (100% duty cycle for both modulators) with time-of-flight mass spectrometry detection. Two exptl. conditions were studied using the same GC³ column set, differing principally in the modulation period from the ¹D to ²D columns: 4 s vs. 8 s. Under the first set of conditions, the average SE_M was 97 (±22), in excellent agreement with the SE_T of 97 (±18). The second set of conditions improved the average SE_M to 181 (±27), also in agreement with the average SE_T of 176 (±26). The average S/N_Rel following correction for the mass spectrum acquisition frequency was 38.8 (±11.2) and 59.0 (±27.2) for the two sets of conditions. The enhancement in S/N is largely attributed to moving the signal to a higher frequency domain where the impact of “low frequency” noise is less detrimental. The findings here provide strong evidence that GC³ separations can provide enhanced detectability relative to 1D-GC and comprehensive two-dimensional gas chromatog. (GCxGC) separations
