Access to Corrole-Appended Persubstituted Benzofurans by a Multicomponent Reaction: The Dual Role of p-Chloranil

A multicomponent reaction among dipyrranes, arylpropargyl aldehydes, and p-chloranil leading to 10-(benzofuran-2yl)corroles is described. p-Chloranil was identified as a crucial reagent playing a twofold role: an oxidant taking part in the formation of the corrole macrocycle and a component undergoing heteroannulation to the incipient 10-arylethynylcorrole. A series of corroles bearing persubstituted benzofuran-2-yl moieties have been synthesized, and their fundamental electronic properties have been studied via UV-vis absorption and fluorescence spectroscopies.

Sulfonate and sulfamate derivatives possessing benzofuran or benzothiophene nucleus as potent carbonic anhydrase II/IX/XII inhibitors

In the current work, we report the discovery of new sulfonate and sulfamate derivatives of benzofuran-and benzothiophene as potent inhibitors of human carbonic anhydrases (hCAs) II, IX and XII. A set of derivatives, 1a-t, having different substituents on the fused benzofuran and benzothiophene rings (R= alkyl, cyclohexyl, aryl, NH2, NHMe, or NMe2) was designed and synthesized. Most of the derivatives exhibited higher potency than acetazolamide as inhibitors of the purified hCAII, IX and XII isoforms. The most potent inhibitors for hCAII, hCAIX and hCAXII were 1g, 1b and 1d with an IC50 +/- SEM values of 0.14 +/- 0.03, 0.13 +/- 0.03 and 0.17 +/- 0.06 mu M, respectively. In addition, compounds 1d and 1n exerted preferential inhibitory effect against hCAXII isozyme with good potencies. Some selected compounds were docked within the active pocket of these isozymes and binding of the molecules revealed that sulfonate and sulfamate rings were located towards the active cavity and compounds coordinated to zinc ions.

Copper-Catalyzed C-H Difluoroalkylation of Coumarins with Fluoroalkyl Bromides

An efficient method for the copper-catalyzed selective C-H difluoroalkylation of coumarins and with low cost and readily available ethyl bromodifluoroacetate andN-phenyl bromodifluoroacetamide has been reported. This reaction exhibits good functional group tolerance with respect to coumarins and difluoroalkylation reagents, and several redox-sensitive substrates have been successfully C-H difluoroalkylated in good to high yield. This design could further expand the scope to other heteroarenes, including furan, benzofuran, pyrrole, pyridinone, chromenone, indole, and quinolinone. A mechanism involving copper-catalyzed in-situ generation of fluoroalkyl radical is proposed.

Theoretical investigation into the mechanism of copper-catalyzed Sonogashira coupling using trans-1,2-diamino cyclohexane ligand

The mechanism of copper-catalyzed Sonogashira coupling reaction employing trans-1,2-diamino cyclohexane ligand have been investigated with Density Functional Theory (DFT) method augmented with Conductor-like Polarizable Continuum Model (CPCM) solvation model. The cross-coupling reactions could be accelerated by employing chelating diamine ligands. Thus, we considered trans-1,2-diamino cyclohexane as the ligand for our study. These coupling reactions find its applicability in the synthesis of aryl acetylenes, the precursors for the various benzofuran derivatives which are present in many biologically important compounds. Considering various reaction pathways possible, it was found that diamine ligated copper (I) acetylide was the active state of the catalyst, which on further reaction with aryl halide undergoes a concerted oxidative addition – reductive elimination process giving the cross coupled product aryl acetylene while regenerating the active catalytic species. Unlike the Pd-catalyzed Sonogashira cross-coupling, there occurs a concerted mechanism owing to the ease of bond formation between Csp(2)-Csp carbon atoms and instability of a Cu (III) metal center. This shows the mechanism of copper-catalyzed cross-couplings are quite different from that of Pd catalyzed reactions. The latter usually involves individual process involving oxidative addition and reductive elimination. The presences of various functional groups on the substrate molecules have a crucial role in determining the feasibility of the reaction. Henceforth, we have investigated the electronic effects of various functional groups in the substrate molecule on the activation barrier of the cross-coupling reaction. (C) 2020 Elsevier Ltd.

Prostaglandins Isolated from the Octocoral Plexaura homomalla: In Silico and In Vitro Studies Against Different Enzymes of Cancer

Prostaglandin A(2)-AcMe (1) and Prostaglandin A(2) (2) were isolated from the octocoral Plexaura homomalla and three semisynthetic derivatives (3-5) were then obtained using a reduction protocol. All compounds were identified through one- and two-dimensional (1D and 2D) nuclear magnetic resonance (NMR) experiments. Additionally, evaluation of in vitro cytotoxic activity against the breast (MDA-MB-213) and lung (A549) cancer cell lines, in combination with enzymatic activity and molecular docking studies with the enzymes p38 alpha-kinase, Src-kinase, and topoisomerase II alpha, were carried out for compounds 1-5 in order to explore their potential as inhibitors of cancer-related molecular targets. Results showed that prostaglandin A(2) (2) was the most potent compound with an IC50 of 16.46 and 25.20 mu g/mL against MDA-MB-213 and A549 cell lines, respectively. In addition, this compound also inhibited p38 alpha-kinase in 49% and Src-kinase in 59% at 2.5 mu M, whereas topoisomerase II alpha was inhibited in 64% at 10 mu M. Enzymatic activity was found to be consistent with molecular docking simulations, since compound 2 also showed the lowest docking scores against the topoisomerase II alpha and Src-kinase (-8.7 and -8.9 kcal/mol, respectively). Thus, molecular docking led to establish some insights into the predicted binding modes. Results suggest that prostaglandin 2 can be considered as a potential lead for development inhibitors against some enzymes present in cancer processes.

Highly Efficient and Selective Electrochemical Synthesis of Substituted Benzothiophenes and Benzofurans in Microcontinuous Flow

A green and practical method for the synthesis of C-3 halogenated benzothiophenes and benzofurans from 2-alkynylthioanisoles or 2-alkynylanisoles and potassium halide was developed under transition-metal- and oxidant-free conditions, employing an assembled electrochemistry continuous-flow system. The carbon and platinum plates were used as the anode and cathode, respectively; KI or KBr not only served as a halogen source but also as an electrolyte. Moderate to good yields of C-3 halogenated benzothiophenes and benzofuran derivatives were obtained under constant current. Notably, the halogen could also be restored at the cathode to obtain C-3 dehalogenated benzothiophenes and benzofurans in high selectivity by adjusting the current and flow rate of the continuous-flow system. Moreover, this reaction could be easily scaled up with good efficiency in the continuous-flow system, which presents major advantages over reactions in a traditional batch.

Synthesis and bioactivity of novel C2-glycosyl benzofuranylthiazoles derivatives as acetylcholinesterase inhibitors

A new series of C2-glycosyl benzofuranylthiazole derivatives was synthesised by the further cyclization of glycosyl thiourea and 2-(bromoacetyl)-benzofuran via Hantzsch’s method. The corresponding 2-(bromoacetyl)-benzofuran derivatives were obtained by the reaction from various salicylaldehydes, and the glycosyl thiourea was prepared through a series of steps from D-Glucosamine. The acetylcholinesterase-inhibitory activities of the products were tested by Ellman’s method. The most active compounds were subsequently evaluated for the 50% inhibitory concentration values. N-(1,3,4,6-tetra-O-benzyl-2-deoxy-beta-D-glucopyranosyl)-4-(5-methoxy-benzofuran-2-yl)-1,3-thiazole-2-amine possessed the best acetylcholinesterase-inhibition activity with a 50% inhibitory concentration of 2.03 +/- 0.26 mu M.

Dual Rh(II)/Pd(0) Relay Catalysis for One-Pot Synthesis of alpha-Quaternary Allylated Indolin-2-ones and Benzofuran-2-ones

Cooperative Rh(II) and Pd(0) dual relay catalysis has been developed, which allowed one-pot synthesis of alpha-quaternary allylated indolin-2-ones and benzofuran-2-ones. The catalytic reaction proceeded through the sequential Rh(II)-catalyzed intramolecular aromatic C(sp(2))-H bond functionalization of alpha-diazo carbonyl compounds, followed by Pd(0)-catalyzed allylic alkylation with allylic carbonates to afford the products in high yields (up to 97%).
