Herein, we present the first report on TiO2 NPs based hybrid nano-reactor designed and synthesized via N-(2-amino ethyl)-3-amino propyl trimethoxy silane (AAPTMS) functionalization of graphene oxide (GO). The assynthesized nano-reactor was characterized by means of several analytical-cum-spectroscopic techniques that support the successful attempt for the synthesis of TiO2@AAPTMS-rGO. Further, the present catalyst was evaluated for its catalytic performance towards an expedient access to biologically relevant synthesis of 2,4,5-triaryl imidazoles. The functional sites of TiO2@AAPTMS-rGO direct the catalysis from the reactant to product with high atom economy, shorter reaction time and excellent yields. Moreover, the present catalyst TiO2@AAPTMS-rGO shows promising reusability for several catalytic cycles. It also provides a robust approach for 2,4,5-triaryl imidazoles with improved performance and without significant loss in catalytic activity. Further, this catalyst can be upgraded for other organic transformations leading to numerous pharmaceuticals and environment benefits.

Precise control over the morphology and size of coordination polymers (CPs) is crucial for extending these inorganic-organic materials to many advanced applications, in particular for heterogeneous catalysis. In this work, two Zn-based CPs, {[Zn-3(idbt)(2)(4,4 ‘-dmbpy)(2)]center dot H2O}(n) (1) and {[Zn-3(idbt)(2)(H2O)(3)]center dot H2O}(n) (2) (H(3)idbt = 5,5 ‘-(1H-imidazole-4,5-diyl)-bis-(2H-tetrazole), 4,4 ‘-dmbpy = 4,4 ”-dimethyl-2,2 ‘-bipyridine), were synthesized through solvothermal reactions. The morphologies and particle sizes of 1 and 2 could be controlled from large scale to nanoscale by regulating the amount of poly(vinyl alcohol) (PVA). Furthermore, for the conversion reactions of nitromethylbenzenes into benzoic acids, the catalytic properties of nanoscale 1 and 2 were much more efficient than those of large size of 1 and 2, because of the benefit of readily accessible active sites in the nanoscale sized particles, which provide a tunable and functionalizable platform for the conversion reaction by minimizing the diffusion distance but do little for the selectivity.

Direct C-S bond coupling is an attractive way to construct aryl sulfur ether, a building block for a variety of biological active molecules. Herein, we disclose an effective model for regioselective thiolation of the aromatic C-H bond by thiol activation instead of arene activation. Strikingly, this method has been applied into anisole derivatives that are not available in the arene activation approach to forge a single thioether isomer with high reactivity.

Triple-negative breast cancer (TNBC) is the most aggressive cancers with a high recurrence rate and rapidly acquired drug resistance among various breast cancer subtypes. There is no specific drug for treatment of TNBC. Discovery of therapeutic agents with unique modes of actions is urgently needed. In this study, a series of seventy parthenolide derivatives was designed, synthesized, and evaluated for their anti-TNBC activities. Compound 7d exhibited the most potent activity against different breast cancer cells with IC50 values ranging from 0.20 mu M to 0.27 mu M, which demonstrated 11.6- to 18.6-fold improvement comparing to that of the parent compound parthenolide with IC50 values of 2.68-4.63 mu M. It is worth to note that 7d was more active than the positive control drug ADR. Moreover, compound 7d could induce apoptosis of SUM-159 cells through mitochondria pathway and cause G1 phase arrest of SUM-159 cells. These findings indicate that compound 7d deserves further studies as a lead compound for ultimate discovery of effective anti-TNBC drug. (C) 2019 Elsevier Masson SAS. All rights reserved.

An article Synthesis and Study of a Dialkylbiaryl Phosphine Ligand; Lessons for Rational Ligand Design WOS:000485211100003 published article about CATALYZED COUPLING REACTIONS; ARYL HALIDES; OXIDATIVE ADDITION; C-C; PALLADIUM; CONVERSION; COMPLEXES; AMINATION; MECHANISM; SECONDARY in [Bryant, Dillon J.; Zakharov, Lev N.; Tyler, David R.] Univ Oregon, Dept Chem & Biochem, 1253 Univ Oregon, Eugene, OR 97403 USA in 2019, Cited 44.

The rational design and synthesis of a novel dialkylbiarylphosphine ligand, 2′-(dimethylphosphine)-2,6-dimethoxy-1,1′-biphenyl (MeSPhos), for palladium-catalyzed C-N cross-coupling reactions is described. Based on previous results, it was hypothesized that a ligand with electronic properties similar to (2-biphenyl)dimethylphosphine (MeJPhos) but with greater steric bulk would allow the cross-coupling of previously inaccessible deactivated aryl chlorides. As predicted, MeSPhos exhibited similar electronic properties to MeJPhos. However, MeSPhos surprisingly showed a significantly smaller steric profile than MeJPhos. In comparison to the widely used CySPhos (2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl), MeSPhos promoted the oxidative addition of highly deactived aryl chlorides for which CySPhos was ineffective, but significantly decreased the rate of reductive elimination. The kinetics of cross-coupling reactions showed that the altered steric and electronic parameters of MeSPhos had a significant impact on the rate of cross-coupling, and the decreased steric bulk had a profound deleterious impact on the catalyst stability. With regard to this latter point, only the most activated aryl chlorides reacted at a sufficient rate to overcome the rate of catalyst decomposition. These results indicate that the relationship between the electron-donating ability of the phosphine ligand and the rate of oxidative addition is complex, and they also illustrate that increasing substitution on the biphenyl structure does not necessarily increase the steric bulk of the ligand.

Perovskite crystal grain size control, grain boundary passivation, and grain bridging are the keys to obtaining high efficiency in perovskite solar cells. A small amount of semi-conducting single-walled carbon nanotubes added to a perovskite active layer can achieve this. In particular, the surfactants attached to the semiconducting single-walled carbon nanotubes a crucial role. In this work, we synthesized a new surfactant, 4,6-di(anthracen-9-yl)-1,3-phenylene bis(dimethylcarbamate), which has a polyaromatic group on one end and a urea-analogue carbamate group on the other end. The polyaromatic anthracene end functions as a nanotweezer clenching the carbon nanotubes strongly via pi-pi interaction while the carbamate end interacts with Pb2+, functioning as a strong Lewis base. In addition, the new surfactant has conjugated double bonds with a suitable bandgap, resulting in enhanced charge mobility in the perovskite film. Overall, the new surfactant-clenched semiconducting carbon nanotubes showcase superior effectiveness as passivators and charge bridges in perovskite solar cells as compared to the conventional deoxycholate surfactant-wrapped semiconducting single-walled carbon nanotubes. The new surfactant-attached semiconducting carbon nanotube-added NH3CH3PbI3-based perovskite solar cells exhibited a power conversion efficiency of 20.7%, which is higher than that of the reference devices with no additives (18.4%) and the previously reported semiconducting single-walled carbon nanotube-added devices (19.7% in this work and 19.5% in the literature).

Transition-metal-catalyzed sp(2) C-N bond formation is a reliable method for the synthesis of aryl amines. Catalytic sp(3) C-N formation reactions have been reported occasionally, and methods that can realize both sp(2) and sp(3) C-N formation are relatively unexplored. Herein, we address this challenge with a method of catalytic decarboxylative C-N formation that proceeds through a cascade carboxylic acid activation, acyl azide formation, Curtius rearrangement and nucleophilic addition reaction. The reaction uses naturally abundant organic carboxylic acids as carbon sources, readily prepared azidoformates as the nitrogen sources, and 4-dimethylaminopyridine (DMAP) and Cu(OAc)(2) as catalysts with as low as 0.1 mol % loading, providing protected alkyl, alkenyl and aryl amines in high yields with gaseous N-2 and CO2 as the only byproducts. Examples are demonstrated of the late-stage functionalization of natural products and drug molecules, stereospecific synthesis of useful alpha-chiral alkyl amines, and rapid construction of different ureas and primary amines.

The electrochemical-induced C-H methylthiolation of electron-rich aromatics has been accomplished via a three component cross-coupling strategy. Potassium thiocyanate (KSCN) as both the supporting electrolyte and sulfur source and methanol as the methylation reagent are used. This protocol is versatile for various (hetero)aromatic compounds such as aniline, anisole and indole. The reaction proceeds under mild conditions without any metal catalyst, exogenous oxidant and highly toxic sulfur reagent. Importantly, such an electrochemical-induced methylthiolated reaction could be easily scaled up with good efficiency.
