Dhananjaya, G.;Venkateshwarlu, Rapolu;Dinne, Naresh Kumar Reddy;Kumar, Avula Mahesh;Mekala, Ramamohan;Anna, Venkateswara Rao;Kapavarapu, Ravikumar;Pal, Manojit research published 《 Wang-OSO₃H catalyzed green synthesis of bioactive isoindolo[2,1-a]quinazoline-5,11-dione derivatives: An unexpected observation》, the research content is summarized as follows. The sulfonic acid-functionalized Wang resin (Wang-OSO₃H) was explored as a polymeric and recoverable acidic catalyst for the synthesis of isoindolo[2,1-a]quinazoline-5,11-diones I (R¹ = H, Cl, Br; R² = Me, HCCCH₂, cyclopropyl, 2-MeOC₆H₄, etc.) under green conditions. Thus, the Wang-OSO₃H catalyzed multicomponent reaction (MCR) of an R¹-substituted isatoic anhydride, 2-formylbenzoic acid and various amines R²NH₂ in pure water afforded a range of desired products I in good to excellent (86-94%) yields. The methodol. could be performed under open air and is amenable for scale-up synthesis. The catalyst could be recovered and recycled for several times without significant loss of its catalytic activity. The unexpected formation of 2-(1-hydroxy-3-oxoisoindolin-2-yl)benzamide derivative as observed in one case may allow the access of this class of heterocycles from the same MCR by using an appropriate amine. In silico assessment suggested that the compound I (R¹ = H; R² = 4-MeOC₆H₄CH₂), a known inhibitor of TNF-α, could be a potential ligand for SARS-CoV-2 with which it formed H-bonds through its OMe and two C=O groups.

A carbene-catalyzed sulfonylation reaction between enone aryl aldehydes and sulfonyl chlorides is disclosed. The reaction effectively installs sulfone moieties in a highly enantioselective manner to afford sulfone-containing bicyclic lactones. The sulfonyl chloride behaves both as an oxidant and a nucleophilic substrate (via its reduced form) in this N-heterocyclic carbene (NHC)-catalyzed process. The NHC catalyst provides both activation and stereoselectivity control on a very remote site of enone aryl aldehyde substrates. Water plays an important role in modulating catalyst deactivation and reactivation routes that involve reactions between NHC and sulfonyl chloride. Exptl. studies and DFT calculations suggest that an unprecedented intermediate and a new oxidation mode of the NHC-derived Breslow intermediate are involved in the new asym. sulfonylation reaction.

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.

A series of coumarin derivatives and isosteres were synthesized from the reaction of triflic intermediates with phenylboronic acids, terminal alkynes, and organozinc compounds through palladium-catalyzed cross-coupling reactions. The in vitro cytotoxic effect of the compounds was evaluated against two non-small cell lung carcinoma (NSCLC) cell lines (A-549 and H2170) and a normal cell line (NIH-3T3) using cisplatin as a reference drug. Addnl., the effects of the most promising coumarin derivative (9f) in reversing the epithelial-to-mesenchymal transition (EMT) in IL-1β-stimulated A549 cells and in inhibiting the EMT-associated migratory ability in A549 cells were also evaluated. 9f had the greatest cytotoxic effect (CC50 = 7.1 ± 0.8 and 3.3 ± 0.5 μM, resp. against A549 and H2170 cells) and CC50 value of 25.8 μM for NIH-3T3 cells. 9f inhibited the IL-1β-induced EMT in epithelial cells by inhibiting the F-actin reorganization, attenuating changes in the actin cytoskeleton reorganization, and downregulating vimentin in A549 cells stimulated by IL-1β. Treatment of A549 cells with 9f at 7 μM for 24 h significantly reduced the migration of IL-1β-stimulated cells, which is a phenomenon confirmed by qual. assessment of the wound closure. Taken together, our findings suggest that coumarin derivatives, especially compound 9f, may become a promising candidate for lung cancer therapy, especially in lung cancer promoted by NSCLC cell lines.
