  新型双萜衍生的双功能硫脲催化剂促进的高对映选择性迈克尔加成反应：手性琥珀酰亚胺衍生物的双立体控制方法

  摘要：

  描述了双立体控制的有机催化不对称迈克尔加成取代琥珀酰亚胺的合成。从醛和马来酰亚胺开始，将两种特殊的手性双萜衍生的双官能硫脲分别用作丁二酰亚胺时，琥珀酰亚胺的两种对映异构体均可以高至优异的收率（高达98％）和对映选择性（高达99％）获得。催化剂。而且，这些催化剂可以有效地用于大规模催化合成，且产率和对映选择性相同。手性00：000–000，2014年。©2014 Wiley Periodicals，Inc.

  amine-squaramides catalyzed asymmetric Michael addition reaction of α,α-disubstituted aldehydes to maleimides has been developed. This organocatalytic asymmetric reaction provides easy access to functionalized succinimides with a broad substrate scope. Both enantiomers of desired succinimide derivatives were obtained in good to excellent yields (up to 98%) with excellent enantioselectivities (up to >99% ee)

• 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.

  Chiral primary amine thiourea catalysts were first successfully applied to promote Michael addition of isobutyraldehyde to maleimides. A variety of N-aryl and N-aliphatic maleimides provided Michael adducts in excellent yields (up to 98%) and enantioselectivities (up to 99% ee) with 5 mol % catalyst. (C) 2010 Elsevier Ltd.
