  摘要：

  本文揭示了几种共轭不饱和酮和腈与羧酸（如乙酰乙酸、丙二酸和氰基乙酸）的脱羧反应。在该反应中，这些羧酸被脱羧，并引入到共轭不饱和化合物的β碳位置。因此，提供了一种有效的方式在该位置引入乙酰基、羧甲基和氰甲基。

  cation ionic liquids (CECILs) were designed, synthesised and characterised by NMR spectroscopy, HRMS, thermogravimetric differential thermal analysis (TG‐DTA) and elemental analysis. Their applications in various organic reactions were investigated: [15‐C‐5Na][OH], [15‐C‐5Na][OAc], [18‐C‐6K][OH] and [18‐C‐6K][OAc] (15‐C‐5=[15]crown‐5; 18‐C‐6=[18]crown‐6) efficiently catalysed the Michael addition of alkenes

  Magnesium oxide (MgO), obtained using a novel but simple procedure, was systematically investigated as a heterogeneous base catalyst for reactions taking place in the liquid phase, specifically the Michael addition and the Knoevenagel condensation. The activity of MgO was studied in detail, together with the effects of solvent and substrate on the catalytic activity for each type of reaction. A key finding is that the formation of enols affected the activity of MgO. The experimental results show that the activity of MgO did not change when it was reused and it is an excellent heterogeneous catalyst for the reactions studied.

  氧化镁（MgO）采用了一种新颖但简单的制备方法，被系统地研究作为液相反应的非均相碱催化剂，具体涉及Michael加成反应和Knoevenagel缩合反应。详细探讨了MgO的活性，以及溶剂和底物对每类反应催化活性的影响。一个关键发现是，烯醇化物的形成影响了MgO的活性。实验结果表明，MgO在重复使用时活性未发生变化，它是所研究反应的一种优秀非均相催化剂。

  An efficient and convenient highly enantioselective Michael addition of malononitrile to enones has been developed by using quinine as the organocatalyst. The adducts were isolated in excellent yield and high asymmetric induction (up to 95% ee). An easy route to difficultly accessible ester derivatives has been also disclosed.

  The highly enantioselective Michael addition of malononitrile to acyclic and cyclic alpha,beta-unsaturated ketones has been developed. The Michael reaction catalyzed by a primary amine derived from quinidine proceeded smoothly and provided the desired adducts with excellent enantioselectivities (83-97% ee).
