  Heterogeneous Jørgensen–Hayashi catalyst for asymmetric Michael addition of malonates to α,β-enals. Cooperative effect with Ca(OTf)2

  摘要：

  Heterogeneous chiral Jorgensen-Hayashi catalyst promotes enantioselective Michael addition of malonates at cinnamic aldehydes. In combination with Ca(OTf)(2), it provides high yields (up to 78%) and excellent enantiomeric excesses (up to 99%) of the adducts.

  Shortcut to chiral catalysts: An efficient combinatorial strategy based on back reaction screening by ESI‐MS allows rapid evaluation of organocatalysts for the asymmetric Michael addition to α,β‐unsaturated aldehydes (see scheme). An unexpected nonlinear effect has been observed in this reaction, resulting from a double nucleophilic–electrophilic activation mechanism involving two catalyst molecules

  手性催化剂的捷径：基于ESI-MS逆反应筛选的有效组合策略可快速评估有机催化剂中α，β-不饱和醛的不对称Michael加成反应（参见方案）。在该反应中观察到了意外的非线性效应，这是由涉及两个催化剂分子的双亲核-亲电活化机制引起的。

  A new catalytic Saegusa oxidation-Michael addition cascade reaction has been developed for the enantioselective beta-functionalization of aldehydes. The feature of this research is the combination of organocatalysis and transition-metal catalysis for the asymmetric C-H functionalization which remains an underdeveloped research topic.

  The Michael addition of malonates to α,β-unsaturated aldehydes catalyzed by O-TMS protected diphenylprolinols and acetic acid in water occurs at 0 °C to rt. In most cases, the reaction runs to completion in less than 24 h. A wide range of aldehydes including β-aryl, β-alkyl and β-alkenyl acroleins are found to be compatible with these conditions, providing the corresponding adducts in good yields and

  丙二酸酯在O -TMS保护的二苯基脯氨醇和水中的乙酸催化下，向α，β-不饱和醛中的迈克尔加成反应在0°C至rt的条件下进行。在大多数情况下，反应会在不到24小时的时间内完成。发现包括β-芳基，β-烷基和β-链烯基丙烯醛在内的多种醛均与这些条件相容，从而以高收率和良好至优异的对映选择性提供相应的加合物。

  [60]fullerene via click chemistry provides a highly efficient supported enantioselective organocatalyst, which was successfully exploited in a Michael addition of malonates to cinnamaldehydes, via iminium ion activation. The supported organocatalyst was recycled up to six times, with only a moderate decrease in terms of activity and with no loss in enantioselectivity.
