The two-electron oxidation of water (2e-WOR) has been studied in the past as a possible method for the alternative preparation of hydrogenperoxide. Often, fluorinated tin oxide (FTO) is used as an anode and FTO itself was found also to be active for 2e-WOR. Because one use of H2O2 is as an oxygen donor for Baeyer–Villiger oxidation of ketones catalyzed by tin compounds and materials, presently we
过去已经研究了水的双电子氧化 (2e-WOR) 作为替代制备过氧化氢的一种可能方法。通常,氟化锡氧化物 (FTO) 用作阳极,并且发现 FTO 本身也对 2e-WOR 具有活性。因为 H 2 O 2的一种用途是作为由锡化合物和材料催化的酮的 Baeyer-Villiger 氧化的氧供体,所以目前我们有兴趣研究在这些反应中原位形成的 H 2 O 2的用途。首先,在乙腈/水溶剂中的 2e-WOR 反应中验证了 H 2 O 2的形成,就 H 2 O而言,这比水中的类似反应更有效在可比较的电位下达到2浓度和法拉第效率,即 ∼3 V vs SHE。其次,对硫化物等反应性底物氧化的初步研究表明,双电子氧化反应的标准化反应速率 (NRR) 比 H 2 O 2形成的 NRR 高约 3 倍,表明形成了活性氧供体或在 H 2 O 2形成和释放之前电极表面上的氧化物质成溶液。第三,2-金刚烷酮在 2.1 V 与乙腈/水中的

Starting from high throughput screening hit 2-adamantyl acetic acid 3, a series of polycyclic acids have been designed and synthesized as novel, potent, and selectiveinhibitors of human 11β-HSD-1. Structure–activity relationships of two different regions of the chemotype (polycyclic ring and substituents on quaternary carbon) are discussed.
