  • Hydride reduction of alpha, beta-unsaturated carbonyl compounds using chiral organic catalysts
    申请人:MacMillan David
    公开号:US20060161024A1
    公开(公告)日:2006-07-20
    Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-hydride reduction of an α,β-unsaturated carbonyl compound. The α,β-unsaturated carbonyl compound may be an aldehyde or cyclic ketone, and the hydride donor may be a dihydropyridine. The reaction is enantioselective, and proceeds with a variety of hydride donors, catalysts, and substrates. The invention also provides compositions effective in carrying out the 1,4-hydride addition of α,β-unsaturated carbonyl compounds.
    非金属手性有机催化剂被用于催化α,β-不饱和羰基化合物的1,4-氢化物还原。α,β-不饱和羰基化合物可以是醛或环酮,氢化物供体可以是二氢吡啶。该反应是对映选择性的,并且可以使用多种氢化物供体、催化剂和底物进行。该发明还提供了用于进行α,β-不饱和羰基化合物的1,4-氢化物加成的有效组合物。

    日期:2012.5.29
    An efficient palladium catalyst is presented for the formation of benzylic quaternary stereocenters by conjugate addition of arylboronic acids to a variety of β,β‐disubstituted carbocyclic, heterocyclic, and acyclic enones. The catalyst is readily prepared from PdCl2, PhBOX, and AgSbF6, and provides products in up to 99 % enantiomeric excess, with good yields. Based on this strategy, (−)‐α‐cuparenone
    通过将芳基硼酸共轭加成到各种β,β-二取代的碳环,杂环和无环烯酮上,提出了一种有效的钯催化剂,用于形成苄基季立体中心。该催化剂易于由PdCl 2,PhBOX和AgSbF 6制备,并以高达99%的对映体过量提供产物。基于此策略,仅需两个步骤即可制备(-)-α-cuparenone。

    日期:2005.1.1
    The first enantioselective organocatalytic hydride reduction has been accomplished. The use of iminium catalysis has provided a new organocatalytic strategy for the enantioselective reduction of beta,beta-substituted alpha,beta-unsaturated aldehydes to generate beta-stereogenic aldehydes. The use of imidazolidinone 2 as the asymmetric catalyst has been found to mediate the transfer of hydrogen to a
    第一次对映选择性有机催化氢化物还原已经完成。亚胺催化剂的使用为β,β-取代的α,β-不饱和醛的对映选择性还原生成β-立体醛提供了一种新的有机催化策略。已发现使用咪唑烷酮 2 作为不对称催化剂可介导氢从 Hantzsch 乙酯到一大类烯醛底物的转移。催化剂 2 在选择性 E-烯烃还原之前加速 EZ 异构化的能力允许在这个操作简单的协议中实施几何不纯的烯醛。
