  A Cooperative Participation of the Amido Group in the Organocatalytic Construction of All-Carbon Quaternary Stereocenters by Michael Addition with β-Ketoamides

  摘要：

  The secondary amido group of a-substituted beta-ketoamides plays a crucial role in the control of the reactivity and spatial arrangement (selectivity) in the organocatalyzed Michael addition to unsaturated carbonyls. This results in an unprecedented activation mode of substrates through H-bonding interactions allowing the construction of enantiomerically enriched functionalized all-carbon quaternary centers and spiroaminals of high synthetic potential.

  The organocatalytic enantioselective conjugate addition of secondary β‐ketoamides to α,β‐unsaturated carbonyl compounds is reported. Use of bifunctional Takemoto’s thiourea catalyst allows enantiocontrol of the reaction leading either to simple Michael adducts or spirocyclic aminals in up to 99 % ee. The origin of the enantioselectivity has been rationalised based on combined DFT calculations and kinetic

  据报道，β-酮酰胺仲胺向α，β-不饱和羰基化合物的有机催化对映选择性共轭加成反应。使用双功能Takemoto's硫脲催化剂可以对反应进行对映体控制，从而导致简单的Michael加合物或高达99％ee的螺环缩醛 。基于组合的DFT计算和动力学分析，对映选择性的起源已经合理化。这项研究提供了对反应机理的更深入的了解，其中涉及仲酰胺质子的主要作用，并阐明了底物与催化剂之间发生的复杂相互作用。
