  • Allylic Oxidations Catalyzed by Dirhodium Catalysts under Aqueous Conditions
    申请人:Doyle Michael P.
    公开号:US20090093638A1
    公开(公告)日:2009-04-09
    The present invention relates to compositions and methods for achieving the efficient allylic oxidation of organic molecules, especially olefins and steroids, under aqueous conditions. The invention concerns the use of dirhodium (II,II) “paddlewheel complexes, and in particular, dirhodium carboximate and tert-butyl hydroperoxide as catalysts for the reaction. The use of aqueous conditions is particularly advantageous in the allylic oxidation of 7-keto steroids, which could not be effectively oxidized using anhydrous methods, and in extending allylic oxidation to enamides and enol ethers.
    本发明涉及在水相条件下实现有机分子的高效烯丙基氧化的组合物和方法,特别是烯烃和类固醇。该发明涉及使用二铑(II,II)“桨轮”配合物,特别是二铑羧酸酯和叔丁基过氧化氢作为催化剂进行反应。在烯丙基氧化7-酮类固醇中使用水相条件特别有优势,无法使用无水方法有效氧化,以及将烯丙基氧化扩展到烯酰胺和烯醇醚。
  • Efficient aziridination of olefins catalyzed by dirhodium catalysts

    公开(公告)日:2006-09-21
    This invention relates to compositions and methods for achieving the efficient aziridination of organic molecules, especially olefins. More specifically, the invention is directed to a mild, selective, and efficient aziridination protocol that involves catalysis by a mixed-valent dirhodium(II,III) catalyst (Rh 2 5+ ). Especially preferred sources for forming such mixed-valent dirhodium(II,III) catalyst (Rh 2 5+ ) are dirhodium(II) carboxamidates, such as dirhodium(II) caprolactamate, and their derivatives and analogues.
    这项发明涉及用于实现有机分子,特别是烯烃的高效环氮化的组合物和方法。更具体地,该发明涉及一种温和、选择性和高效的环氮化方案,涉及通过混合价二铑(II,III)催化剂(Rh25+)进行催化。特别偏好用于形成这种混合价二铑(II,III)催化剂(Rh25+)的来源是二铑(II)羧酰胺酸盐,例如二铑(II)己内酰胺酸盐,以及它们的衍生物和类似物。

In contrast, the intramolecular aziridination of several cycloalkenyl-substituted carbamates did not require a Rh(II) catalyst and proceeded via an iminoiodinane intermediate. The resulting tricyclic aziridines underwent ring opening when treated with various nucleophiles to give anti-derived products as expected for nucleophilic attack at the three-membered ring.
