  Synthesis and antiulcer activity of novel 5-(2-ethenyl substituted)-3(2H)-furanones

  摘要：

  In order to investigate new antiulcer agents, spizofurone 1 (AG-629) was fragmented and reassembled to generate 5-phenyl-2,2-dimethyl-3(2H)-furanone (bullatenone, 2). Because of the antiulcer activity of 2,5-phenyl-substituted 2,2-dimethyl-3(2H)-furanones (3-6) were made and shown to have poor activity. Insertion of an ethenyl link between the furanone and phenyl rings gave 5-(2-phenylethenyl)-2,2-dimethyl-3(2H)-furanone (7). This compound had better activity than 2. Compounds 8-41 were synthesized to evaluate the SAR in 5-(2-ethenyl substituted)-3(2H)-furanones. Electron-withdrawing substituents on the aromatic ring (8, 10, 19, and 20) gave 2-3-fold higher activity. Further increases in the activity were found when the phenyl ring was replaced by heterocyclic nuclei. Compounds that contained a thiophene (29), pyridine (24-26), or quinoline ring (32) had the best activity. Replacement of the methyl group on the furanone ring with a phenyl (34) or p-fluorophenyl (40) substituent in the 2-pyridine series gave compounds with activity that ranked with the best obtained in this study. The best compounds from the above SAR studies were evaluated in the ethanol-necrosis model for duration of cytoprotection action. Compounds 19, 24, and 29, which had the best duration of action, were tested with AG-629 in the acidified aspirin and indomethacin-induced lesion models. Only compound 24 had equivalent activity with AG-629 in both models.

  在温和条件下以吡啶基苯并咪唑（PBI）作为二齿N-螯合配体的铜催化合成3,5-二取代异恶唑

  摘要：

  在本文中，我们引入了吡啶基苯并咪唑（PBI）作为易于处理的二齿N-螯合配体，该配体在乙酸铜作为催化剂的存在下促进3,5-二取代异恶唑的清洁合成。这种催化方法是先进行醛的羟基胺化反应，然后进行氯化反应，然后生成一氧化氮，然后与炔烃进行点击型[3 + 2]-偶极环加成反应，生成异恶唑。该方法为构建异恶唑衍生物提供了另一种绿色工艺。

  nanohybrid) as a highly efficient heterogeneous nano-catalyst is described. In this method, Cu/AC/r-GO nanohybrid catalyses the 1,3-dipolar cycloaddition of alkynes and nitrile oxides in the presence of NaHCO3 in H2O/THF (50:50, V/V) to afford the corresponding 3,5-disubstituted isoxazoles. The Cu/AC/r-GO nanohybrid is a low cost, non-hygroscopic, chemically and thermally stable catalyst that can be reused

  A series of substituted tetrahydropyrrolo[2,1-b]oxazol-5(6H)-one and tetrahydropyrrolo[2,1-b]thiazol-5(6H)-ones was synthesized from amino alcohols or amino thiols and keto acids. A pharmacological model based on the results obtained with these compounds led to the synthesis and evaluation of a series of isoxazoles and other monocyclic compounds. These were evaluated for their ability to enhance glucose utilization in cultured L6 myocytes. The in vivo hypoglycemic efficacy and potency of these compounds were evaluated in a model of type 2 diabetes mellitus (non-insulin-dependent diabetes mellitus), the ob/ob mouse. 25a(2S) (SDZ PGU 693) was selected for further pharmacological studies.

  promote clean synthesis of 3,5-disubstituted isoxazoles in the presence of copper acetate as catalyst. This catalytic approach initiates with the hydroxyamination of aldehydes followed by chlorination and then generation of nitrile oxide which subsequently undergoes click-type [3 + 2]-dipolar cycloaddition with alkynes to give isoxazoles. This method provides an alternative green process to construct isoxazole
