    铜催化加氢胺化合成对映体富集的N-芳基胺的改进系统
    摘要:
    尽管最近在铜催化的对映选择性氢化胺化化学方面取得了重大进展,但尚未实现在天然产物和药物中经常发现的手性N-芳基胺的合成。N的初步实验‐芳基羟胺酯亲电试剂未成功,相反,它们在氢化铜(CuH)催化剂存在下被还原。本文中,我们报告了对我们先前报道的加氢胺化方法的关键修改,这些修改为在苯乙烯,1,1-二取代的烯烃和末端烯烃的双键上对仲苯胺的对映选择性净加成条件提供了广泛适用的条件。NMR研究表明,抑制不希望有的还原途径是根据报道的方法显着提高收率的基础。

  • Synthesis of 3-Alkylbenzoxazolones from <i>N</i>-Alkyl-<i>N</i>-arylhydroxylamines by Contiguous <i>O</i>-Trichloroacetylation, Trichloroacetoxy <i>ortho</i>-Shift, and Cyclization Sequence
    作者:Ram N. Ram、Vineet Kumar Soni

    Benzoxazolone pharmacophore is present in clinical pharmaceuticals, drug candidates, and many compounds having a wide spectrum of biological activities. The methods available for the synthesis of benzoxazolones have limited diversity due to problems in accessibility and air-sensitivity of diversely substituted o-aminophenols from which they are generally prepared by cyclocarbonylation with phosgene or its equivalents. The present paper describes a mild method for the synthesis of 3-alkylbenzoxazolones from easily accessible and air-stable nitroarenes. Nitroarenes were converted to N-alkyl-N-arylhydroxylamines in two steps involving partial reduction to arylhydroxylamines followed by selective N-alkylation. Treatment of N-alkyl-N-arylhydroxylamines with trichloroacetyl chloride and triethylamine afforded 3-alkylbenzoxazolones generally in good yields through an uninterrupted three-step sequence involving O-trichloroacetylation, N -> C-ortho trichloroacetoxy shift, and cyclization in a single pot at ambient temperatures. The present method is mild, wide in scope, economical, and regioselective. Many sensitive groups like alkyl and aryl esters, amide, cyano, and the carbon-carbon double bond survive the reaction.
