    Preparation of α-Imino Aldehydes by [1,3]-Rearrangements of O-Alkenyl Oximes
    摘要:
    The synthesis of alpha-imino aldehydes has been achieved through the thermal [1,3]-rearrangement of O-alkenyl benzophenone oximes. A copper. mediated C-O bond coupling between benzophenone oxime and alkenyl boronic acids provides facile access to the required O-alkenyl oximes and a Horner-Wadsworth-Emmons olefination can be applied to the a-imino aldehyde products to give gamma-imino-alpha,beta-unsaturated esters. The scope of the method is described and mechanistic experiments are discussed.

  • One-Pot Synthesis of Trisubstituted Conjugated Dienes via Sequential Suzuki−Miyaura Cross-Coupling with Alkenyl- and Alkyltrifluoroborates
    作者:Gary A. Molander、Yasuo Yokoyama
    DOI:10.1021/jo052636k
    日期:2006.3.1
    Pd(PPh3)4 is described. This synthetic method proceeds smoothly in one pot under mild reaction conditions to provide the corresponding trisubstituted, conjugated dienes in excellent yield. Moreover, the method is operationally very simple because the organotrifluoroborates are stable in air, and the byproducts are innocuous inorganic salts.
