标题:Identification And Biosynthesis Of Tropone Derivatives And Sulfur Volatiles Produced By Bacteria Of The Marine Roseobacter Clade
摘要:Roseobacter 支系的细菌是丰富的海洋细菌,是全球硫循环的重要贡献者.研究人员分析了其中两个成员 Phaeobacter Gallaeciensis 和 oceanibulbus Indolifex 产生的挥发性物质,以研究释放的化合物是否来自硫代谢,以及形成这些化合物的生物合成途径.两种细菌都释放出不同的硫化物和硫代酯,包括新的天然化合物,如 S-甲基苯硫酸盐(16)和甲基磺酸丁酯(21).这些 S-甲基烷酸酯是通过与标准品进行比较而鉴定出来的,标准品是通过使用一种易于制备的铝/硫试剂的新方法从相应的甲基烷酸酯中合成的.加拉埃希氏芽孢杆菌也能大量生产托品酮(37).通过各种喂养实验对其生物合成进行了研究,结果表明 37 是通过苯乙酸分解代谢的偏差形成的.不稳定的托品酮水合物 42 被确定为托品酮生物合成的中间产物,它也会与托品酮一起释放出来(38).

标题 :Synthesis of oxindoles from anilines and intermediates therein
摘要:Preparing oxindoles and intermediates therefor by reacting an N-haloaniline with β-thio ester or β-thio amides to form an azasulfonium halide, reacting the azasulfonium halide with a base to form an ortho[thio-ether (hydrocarbonoxycarbonyl) alkyl]aniline, or a [thio-ether (aminocarbonyl) alkyl]aniline, reacting the ortho-substituted aniline with an acid to form a 3-thio-ether-2-oxindole, and then reducing the 3-thio-ether-2-oxindole with Raney Nickel to form the 2-oxindole.
