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。
