  钌（II）催化的脱羰环化反应合成螺并苯并呋喃酮

  摘要：

  据报道，炔烃通过六元化合物的C / H / C-C活化而首次脱羰基插入。在配体PPh 3存在下，Ru-催化的3-羟基-2-苯基色酮与炔烃的反应最有效，可提供螺茚二苯并呋喃酮。与以前报道的金属催化的脱羰环化反应不同，在本脱羰环化反应中，环化发生在一氧化碳挤出之前。

• Understanding the Cardioprotective Effects of Flavonols: Discovery of Relaxant Flavonols without Antioxidant Activity

  3 ',4 '-Dihydroxyflavonol (DiOHF) is a cardioprotective flavonol that can reduce injury after myocardial ischemia and reperfusion and thus is a promising small molecule for the treatment of cardiovascular disease. Like all vasoactive flavonols reported to date, DiOHF is both relaxant and antioxidant, hindering investigation of the relative contribution of each activity for the prevention of reperfusion injury. This study investigates structure-activity relationships of variations at the 3 ' and 4 ' positions of the B ring of DiOHF and vasorelaxant and antioxidant activities. Relaxation of rat isolated aortic rings precontracted with KCl revealed that the most active flavonols were those with a 4 '-hydroxyl group, with the opening of potassium channels as a possible contributing mechanism. For the antioxidant activity, with the exception of DiOHF, none of the flavonols investigated were able to significantly scavenge superoxide radical, and none of the three most potent vasorelaxant flavonols could prevent oxidant-induced endothelial dysfunction. The discovery of single-acting vasorelaxant flavonols without antioxidant activity, in particular 4 '-hydroxy-3 '-methoxyflavonol, will assist in investigating the mechanism of flavonol-induced cardioprotection.
• Exploring 3-hydroxyflavone scaffolds as mushroom tyrosinase inhibitors: synthesis, X-ray crystallography, antimicrobial, fluorescence behaviour, structure-activity relationship and molecular modelling studies

  To explore new scaffolds as tyrosinase enzyme inhibitors remain an interesting goal in the drug discovery and development. In due course and our approach to synthesize bioactive compounds, a series of varyingly substituted 3-hydroxyflavone derivatives (1-23) were synthesized in one-pot reaction and screened forin vitroagainst mushroom tyrosinase enzyme. The structures of newly synthesized compounds were unambiguously corroborated by usual spectroscopic techniques (FTIR, UV-Vis,H-1-,C-13-NMR) and mass spectrometry (EI-MS). The structure of compound15was also characterized by X-ray diffraction analysis. Furthermore, the synthesized compounds (1-23) were evaluated for their antimicrobial potential. Biological studies exhibit pretty good activity against most of the bacterial-fungal strains and their activity is comparable to those of commercially available antibioticsi.e.Cefixime and Clotrimazole. Amongst the series, the compounds2, 4, 5, 6, 7, 10, 11, 14and22exhibited excellent inhibitory activity against tyrosinase, even better than standard compound. Remarkably, the compound2(IC50= 0.280 +/- 0.010 mu g/ml) was found almost sixfold and derivative5(IC50= 0.230 +/- 0.020 mu g/ml) about sevenfold more active as compared to standard Kojic acid (IC50=1.79 +/- 0.6 mu g/ml). Moreover, these synthetic compounds (1-23) displayed good to moderate activities against tested bacterial and fungal strains. Their emission behavior was also investigated in order to know their potential as fluorescent probes. The molecular modelling simulations were also performed to explore their binding interactions with active sites of the tyrosinase enzyme. Limited structure-activity relationship was established to design and develop new tyrosinase inhibitors by employing 2-arylchromone as a structural core in the future. Communicated by Ramaswamy H.

  activation of six‐membered compounds is reported. The Ru‐catalyzed reaction of 3‐hydroxy‐2‐phenyl‐chromones with alkynes works most efficiently in the presence of the ligand PPh3 to provide spiro‐indenebenzofuranones. Unlike previously reported metal‐catalyzed decarbonylative annulation reactions, in the present decarbonylative annulation reaction, the annulation occurs before extrusion of carbon monoxide
