  新型伯胺-方酸双酰胺双官能团有机催化剂催化α，α-二取代醛向马来酰亚胺的高度对映选择性迈克尔加成反应

  摘要：

  已开发出新的双官能伯胺-方酸酰胺催化α，α-二取代醛与马来酰亚胺的不对称迈克尔加成反应。这种有机催化不对称反应可轻松获得具有广泛底物范围的官能化琥珀酰亚胺。所需琥珀酰亚胺衍生物的两种对映异构体均以良好至优异的产率（高达98％）和优异的对映选择性（高达> 99％ee）获得。

  A doubly stereocontrolled organocatalytic asymmetric Michael addition to the synthesis of substituted succinimides is described. Starting from aldehydes and maleimides, both enantiomers of the succinimides could be obtained in high to excellent yields (up to 98%) and enantioselectivities (up to 99%) when one of the two special chiral diterpene‐derived bifunctional thioureas was individually used as

• A highly efficient large-scale asymmetric Michael addition of isobutyraldehyde to maleimides promoted by a novel multifunctional thiourea

  A novel class of chiral multifunctional thioureas bearing a chiral lipophilic beyerane scaffold and a primary amino group were designed and prepared. The thioureas were proven to be effective for catalyzing the asymmetric Michael addition between isobutyraldehyde and maleimides with only 0.5 mol% catalyst loading, and exhibited double asymmetric induction. Both of the catalysts afforded the corresponding adduct with high to excellent yields (up to 98%) and excellent enantioselectivities (up to 99%). Furthermore, this catalytic system can be used efficiently in large-scale reactions with the yields and enantioselectivities being maintained at the same level. (C) 2011 Elsevier Ltd.
