    amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic aldehydes, conjugate aldehydes, and aliphatic aldehydes. Central to successfully driving the condensation series is the formation

  • Synthesis of β- and β,β-substituted Morita–Baylis–Hillman adducts using a two-step protocol
    作者:David I. Magee、Same Ratshonka、Jessica McConaghy、Maggie Hood
    DOI:10.1139/v2012-017
    日期:2012.5

    The synthesis of a large number of β- and β,β-substituted keto esters was successful by the use of the Knoevenagel condensation reaction. The stereoselectivity of these reactions was improved by alteration of various substituent groups. Although there were few examples of complete Z selectivity, the use of tert-butyl acetoacetate with either aromatic or aliphatic aldehydes afforded Z selectivity. The selective reductions of these substituted keto esters was successfully achieved by using a combination of NaBH4 and CeCl3·7H2O or Yb(OTf)3, which allowed a facile synthesis of a large number of stereochemically pure substituted Morita–Baylis–Hillman adducts, including β,β-substituted adducts.

    大量β-和β,β-取代酮酯的合成成功地通过Knoevenagel缩合反应实现。通过改变各种取代基团来改善这些反应的立体选择性。尽管完全Z选择性的例子很少,但是使用叔丁基乙酰乙酸酯与芳香族或脂肪族醛可以获得Z选择性。这些取代酮酯的选择性还原成功地通过使用NaBH4和CeCl3·7H2O或Yb(OTf)3的组合实现,从而实现了大量立体化纯净的取代Morita–Baylis–Hillman加合物的简便合成,包括β,β-取代加合物。
  • Stereochemical Behavior of Intermediary Compounds in the Amine-Catalyzed Knoevenagel Reaction

    日期:1988.9
    intermediary amino compounds are isolated. The reaction involves many reversible steps, and the stereochemistry of products is determined in the elimination step from the intermediary compounds via stable planar carbanions, in which the small difference in the steric requirements of two electron-withdrawing groups is effective. Steric and electronic effects in the intermediates sometimes bring about the
    用催化量的仲胺处理活性亚甲基化合物和醛可产生热力学稳定的烯烃,并分离出中间氨基化合物。该反应涉及许多可逆步骤,产物的立体化学是在中间化合物通过稳定的平面碳负离子消除步骤中确定的,其中两个吸电子基团的空间要求的微小差异是有效的。中间体中的空间和电子效应有时会随着活性亚甲基化合物的回收而导致碳-碳键裂变,这些效应阻止了 Knoevenagel 反应的发生。
