• Origin of the Enantioselectivity in Organocatalytic Michael Additions of β-Ketoamides to α,β-Unsaturated Carbonyls: A Combined Experimental, Spectroscopic and Theoretical Study

  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。

  The phosphine-catalyzed substrate-dependent (4 + 2) annulations of δ-acetoxy allenoates with ketones is described. Allenoates 1 with an alkyl substituent at δC are able to react with cyclic 1,3-diketones 2, wherein the δC is attacked by the methenyl carbon of 2 while the αC attacks the ketone of 2. Allenoates 5 with an aryl group at δC is poised to react with cyclic β-carbonyl amides 6, in which the

  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.
• Activation of 1,2- and 1,3-Ketoamides with Thiourea Organocatalyst for the Enantioselective Domino Synthesis of Functionalized Cyclohexanes

  Several reactive sites of 1,2- and 1,3-ketoamides were successively exploited in two complementary domino transformations for the synthesis of polysubstituted monocyclic or bridged bicyclic cyclohexanes, with the creation of up to six stereogenic centers. In both cases, a chiral bifunctional thiourea organocatalyst allowed efficient control of chirality in the final carbocycle.
