  • Formation, Alkylation, and Hydrolysis of Chiral Nonracemic <i>N</i>-Amino Cyclic Carbamate Hydrazones: An Approach to the Enantioselective α-Alkylation of Ketones
    作者:Uyen Huynh、Stacey L. McDonald、Daniel Lim、Md. Nasir Uddin、Sarah E. Wengryniuk、Sumit Dey、Don M. Coltart

    as α-functionalized ketones or derivatives thereof. We previously reported our preliminary studies on the development of a new enantioselective ketone α-alkylation procedure using N-amino cyclic carbamate (ACC) auxiliaries. In comparison to other auxiliary-based methods, ACC alkylation offers a number of advantages and is both highly enantioselective and high yielding. Herein, we provide a full account
    酮的α-烷基化是基本的合成转化。鉴于许多天然产物,药物和相关化合物以α-官能化的酮或其衍生物形式存在,因此开发该反应的不对称变体非常重要。我们以前曾报道过使用N-氨基环状氨基甲酸酯(ACC)助剂开发新的对映选择性酮α-烷基化程序的初步研究。与其他基于辅助方法的方法相比,ACC烷基化具有许多优势,并且具有高对映选择性和高收率。在此,我们全面介绍了对映选择性ACC酮α-烷基化方法的研究。

    DOI:10.1021/ja0465193
    日期:2004.9.1
    A zinc enamide generated from the corresponding N-aryl imine undergoes addition to an unactivated olefin, such as ethylene, 1-octene, and isobutylene, to generate an alpha-alkylated gamma-zincioimine intermediate in good to excellent yield. Terminal and gem-disubstituted olefins react with >99% regioselectivity, allowing the C-C bond formation to take place at the more hindered carbon of the double
    由相应的 N-芳基亚胺生成的锌烯酰胺与未活化的烯烃(例如乙烯、1-辛烯和异丁烯)加成,以良好至极好的收率生成 α-烷基化 γ-锌亚胺中间体。末端和偕二取代的烯烃以>99% 的区域选择性反应,使得 CC 键的形成发生在双键的受阻更大的碳上。有机锌中间体与碳亲电子试剂进一步形成 CC 键,在亚胺水解后,生成带有各种官能化伯、仲和叔烷基的 α-烷基化酮。
  • Synthese de cetones aliphatiques encombrees
    作者:C. Lion、J.E. Dubois

    日期:1973.1
    4-dimethyl-2-oxazolines, 4, after hydrolysis of the intermediate enamine. Alkylation of the latter also permits the synthesis of α,α,α-trisubstituted ketones. α,α-Disubstituted ketones have been prepared by addition of organometallic reagents to 4,4-dimethyl-2-oxazolinium salts, 6. The efficiency of this method has been compared to that of other currently used methods.
    α,α-二取代的酮由中间体烯胺水解后有机锂化合物与取代的4,4-二甲基-2-恶唑啉4反应生成。后者的烷基化还允许合成α,α,α-三取代的酮。通过将有机金属试剂添加到4,4-二甲基-2-恶唑啉鎓盐6中,可以制备出α,α-二取代的酮。已将该方法的效率与其他当前使用的方法进行了比较。
