Demonti, Luca;Saffon-Merceron, Nathalie;Mezailles, Nicolas;Nebra, Noel research published 《 Cross-Coupling through Ag(I)/Ag(III) Redox Manifold》, the research content is summarized as follows. Trifluoromethyl argentates(III) undergo reductive elimination with arylboronic acids, yielding trifluoromethylarenes. In ample variety of transformations, the presence of silver as an additive or co-catalyst is believed to be innocuous for the efficiency of the operating metal catalyst. Even though Ag additives are required often as coupling partners, oxidants or halide scavengers, its role as a catalytically competent species is widely neglected in cross-coupling reactions. Most likely, this is due to the erroneously assumed incapacity of Ag to undergo 2e^– redox steps. Definite proof is herein provided for the required elementary steps to accomplish the oxidative trifluoromethylation of arenes through Ag^I/Ag^III redox catalysis (i. e. CEL coupling), namely: (i) easy Ag^I/Ag^III 2e^– oxidation mediated by air; (ii) bpy/phen ligation to Ag^III; (iii) boron-to-Ag^III aryl transfer; and (iv) ulterior reductive elimination of benzotrifluorides from an [aryl-Ag^III-CF₃] fragment. More precisely, an ultimate entry and full characterization of organosilver(III) compounds [K]⁺[Ag^III(CF₃)₄]^– (K-1), [(bpy)Ag^III(CF₃)₃] (2) and [(phen)Ag^III(CF₃)₃] (3), is described. The utility of 3 in cross-coupling has been showcased unambiguously, and a large variety of arylboron compounds was trifluoromethylated via [Ag^III(aryl)(CF₃)₃]^– intermediates. This work breaks with old stereotypes and misconceptions regarding the inability of Ag to undergo cross-coupling by itself.

Dekkiche, Herve;Malincik, Juraj;Prescimone, Alessandro;Haussinger, Daniel;Mayor, Marcel research published 《 An Ortho-Tetraphenylene-Based “Gelander” Architecture Consisting Exclusively of 52 sp²-Hybridized C Atoms》, the research content is summarized as follows. A new type of “Gelander” mol. based on a ortho-tetraphenylene core is presented. The central para-quaterphenyl backbone is wrapped by a 4,4′-di((Z)-styryl)-1,1′-biphenyl banister, with its aryl rings covalently attached to all four Ph rings of the backbone. The resulting helical chiral bicyclic architecture consists exclusively of sp²-hybridized carbon atoms. The target structure was assembled by expanding the central ortho-tetraphenylene subunit with the required addnl. Ph rings followed by a twofold macrocyclization. The first macrocyclization attempts based on a twofold McMurry coupling were successful but low yielding; the second strategy, profiting from olefin metathesis, provided satisfying yields. Hydrogenation of the olefins resulted in a saturated derivative of similar topol., thereby allowing the interdependence between saturation and physico-chem. properties to be studied. The target structures, including their solid-state structures, were fully characterized. The helical chiral bicycle was synthesized as a racemate and separated into pure enantiomers by HPLC on a chiral stationary phase. Comparison of recorded and simulated chiroptical properties allowed the enantiomers to be assigned.

De Tovar, Jonathan;Rataboul, Franck;Djakovitch, Laurent research published 《 From the grafting of NHC-based Pd(II) complexes onto TiO₂ to the in situ generation of Mott-Schottky heterojunctions: The boosting effect in the Suzuki-Miyaura reaction. Do the evolved Pd NPs act as reservoirs?》, the research content is summarized as follows. The assumption that the real active species involved in the Suzuki-Miyaura reaction are homogeneous, heterogeneous or both is often proposed. However a lack of characterization of the true catalytic entities and their monitoring makes assumptions somewhat elusive. Here, with the aim of getting new insights into the formation of active species in the Suzuki-Miyaura reaction, a family of palladium(II) complexes bearing bis(NHC) ligands was synthesized for immobilization at the surface of TiO₂. The studies reveal that once the complexes are anchored onto TiO₂, the mechanism governing the catalytic reaction is different from that observed for the non-anchored complexes. All complexes evolved to Pd NPs at the surface of TiO₂ under reaction conditions and released Pd species in the liquid phase. Also, this reactivity was boosted by the in situ generation of Mott-Schottky heterojunctions, opening new routes towards the design of heterogenized catalysts for their further implementation in reverse-flow reactors.

Davis, Jacqkis;Gharaee, Mojgan;Karunaratne, Chamini V.;Cortes Vazquez, Jose;Haynes, Mikayla;Luo, Weiwei;Nesterov, Vladimir N.;Cundari, Thomas;Wang, Hong research published 《 Asymmetric Synthesis of Chromans Through Bifunctional Enamine-Metal Lewis Acid Catalysis》, the research content is summarized as follows. Cooperative enamine-metal Lewis acid catalysis has emerged as a powerful tool to construct carbon-carbon and carbon-heteroatom bond forming reactions. A concise synthetic method for asym. synthesis of chromans from cyclohexanones and salicylaldehydes has been developed to afford tricyclic chromans containing three consecutive stereogenic centers in good yields (up to 87%) and stereoselectivity (up to 99% ee and 11 : 1 : 1 dr). This difficult organic transformation was achieved through bifunctional enamine-metal Lewis acid catalysis. It is believed that the strong activation of the salicylaldehydes through chelating to the metal Lewis acid and the bifunctional nature of the catalyst accounts for the high yields and enantioselectivity of the reaction. The absolute configurations of the chroman products were established through X-ray crystallog. DFT calculations were conducted to understand the mechanism and stereoselectivity of this reaction.

Dash, Shruti Gamya;Kantevari, Srinivas;Pandey, Swaroop Kumar;Naik, Pradeep Kumar research published 《 Synergistic interaction of N-3-Br-benzyl-noscapine and docetaxel abrogates oncogenic potential of breast cancer cells》, the research content is summarized as follows. Noscapine, an opium alkaloid, was discovered to bind tubulin, arrest dividing cells at mitosis, and selectively induce apoptosis to cancer cells. N-3-Br-Benzyl-Noscapine (Br-Bn-Nos), one of the derivatives of noscapine, was demonstrated to have improved anticancer potential compared with noscapine. We approached to evaluate the single and combined effect of Br-Bn-Nos and docetaxel (DOX) based on mol. modeling and cellular study. The individual predicted free energy of binding (ΔGbind,pred) for Br-Bn-Nos and DOX with tubulin was found to be -28.89 and -36.07 kcal/mol based on mol. mechanics generalized Born solvation area (MM-GBSA) as well as -26.21 and -34.65 kcal/mol based on mol. mechanics Poisson Boltzmann solvation area (MM-PBSA), resp. However, the ΔGbind,pred of Br-Bn-Nos was significantly reduced (-33.02 and -30.24 kcal/mol using MM-GBSA and MM-PBSA) in the presence of DOX on its binding pocket. Parenthetically, the ΔGbind,pred of DOX was significantly reduced (-37.17 and -32.80 kcal/mol using MM-GBSA and MM-PBSA) in the presence of Br-Bn-Nos on its binding pocket. The reduced ΔGbind,pred in the presence of Br-Bn-Nos and DOX together indicated a combination effect of both the ligands. The combined interaction of both the agents onto tubulin dimmer was also determined exptl. using purified tubulin, in which a combination regimen of Br-Bn-Nos and DOX reduced the fluorescence intensity of tubulin to a higher value (68%) compared with the single regimen. Further, isobologram anal. revealed the synergistic effect of Br-Bn-Nos and DOX in antiproliferative activity using MCF-7 cell line at 48 h (sum FIC = 0.49) and at 72 h (sum FIC = 0.62). The combination dose regimen of Br-Bn-Nos and DOX blocks the cell cycle progression at the G2/M phase and induces apoptosis to cancer cells more effectively compared with the single regimen. Taken together, our study provides compelling evidence that the anticancer potential of noscapine derivatives may be substantially improved when it is used in a combined application with DOX for breast cancer.
