  摘要：

  本发明的一个方面部分涉及简单有机底物中未活化C-H键的催化和对映选择性官能团化。本发明提供的化合物和方法允许在C-H活化步骤中控制立体化学，活化含有邻近导向基团的α-氢的底物，并在温和条件下移除导向基团。本发明的另一方面涉及一种过渡金属催化的方法，用于选择性和非对称氧化位于辅助基团β-或Ϝ-位置上的碳。发明的另一个方面涉及通过所述方法形成的对映体富集的底物和对映体富集的产品。在某些实施例中，使用了恶唑啉和恶嗪酮导向基团。此外，Boc保护基团被识别为不需要移除的导向基团。

  Nucleophilic Acyl Substitutions of Anhydrides with Protic Nucleophiles Catalyzed by Amphoteric, Oxomolybdenum Species

  摘要：

  [GRAPHICS]Among six different group VIb oxometallic species examined, dioxomolybdenum dichloride and oxomolybdenum tetrachloride were the most efficient catalysts to facilitate nucleophilic acyl substitution (NAS) of anhydrides with a myriad array of alcohols, amines, and thiols in high yields and high chemoselectivity. In contrast to the well-recognized redox chemical behaviors associated with oxomolybdenum(VI) species, the catalytic NAS was unprecedented and tolerates virtually all kinds of functional groups. By using benzoic anhydride as a mediator for in situ generation of an incipient mixed anhydride -MoO2Cl2 adduct with a given functional alkanoic acid, one can achieve oleate, dipeptide, diphenylmethyl, N-Fmoc-alpha-amino, pyruvic, and tert-butylthio ester, N-tert-butylamide, and trityl methacrylate syntheses with appropriate protic nucleophiles. The amphoteric character of the Mo=O unit in oxomolybdenum chlorides was found to be responsible for the catalytic NAS profile as supported by a control NAS reaction of using an authentic adduct-MoOCl2(O-2-CBut)(2) between pivalic anhydride and MoO2Cl2 as the catalyst.
