Supported Au nanoparticles on TiO2 catalyze the unprecedented dehydrogenative disilylation of monosubstituted and 1,1‐disubstituted allenes by Et2SiH2 exclusively on the terminal double bond in a stereoselective manner. Treatment of the disilylation products with H2O, in a one‐pot operation also catalyzed by Au/TiO2, leads to 3‐alkylidene‐1,2,5‐oxadisilolanes, an unknown class of heterocyclic compounds
在TiO支持的Au纳米颗粒2催化单取代和1,1-二取代的丙二烯的前所未有脱氢disilylation通过的Et 2的SiH 2只在以立体选择性方式的末端双键。在同样由Au / TiO 2催化的一锅操作中,用H 2 O处理二烯丙基化产物会生成3-亚烷基-1,2,5-恶二硅环酮,这是一类未知的杂环化合物,是出色的支架Hiyama型交叉偶联条件下烯烃的立体选择性合成。
The present invention provides pharmacological compounds including an effector moiety conjugated to a binding moiety that directs the effector moiety to a biological target of interest. Likewise, the present invention provides compositions, kits, and methods (e.g., therapeutic, diagnostic, and imaging) including the compounds. The compounds can be described as a protein interacting binding moiety-drug conjugate (SDC-TRAP) compounds, which include a protein interacting binding moiety and an effector moiety. For example, in certain embodiments directed to treating cancer, the SDC-TRAP can include an Hsp90 inhibitor conjugated to a cytotoxic agent as the effector moiety.
Highly selective and direct electroreductive ring-opening carboxylation of epoxides with CO2 in an undivided cell to yield synthetically important β-hydroxy acids is described. CO2functions not only as a carboxylative reagent in this reaction but also as a promoter to enable efficient and chemoselective transformation of epoxides under additive-free electrochemical conditions.
描述了在未分裂的电池中用 CO 2对环氧化物进行高选择性和直接的还原性开环羧化,以产生合成重要的β-羟基酸。CO 2不仅在该反应中充当羧化试剂,而且还充当促进剂以在无添加剂的电化学条件下实现环氧化物的有效和化学选择性转化。
