  • Organocatalytic Asymmetric Alkylation of Aldehydes by SN1-Type Reaction of Alcohols
    作者:Pier Giorgio Cozzi、Fides Benfatti、Luca Zoli
    DOI:10.1002/anie.200805423
    日期:2009.2.2
    Work‐alcoholic! The elusive enantioselective catalytic α‐alkylation of aldehydes, a widely sought transformation, was brought to execution by the use of alcohols capable of forming stabilized carbocations (see scheme, TFA=trifluoroacetic acid).
    工作酒精!醛类难以捉摸的对映选择性催化α-烷基化反应,是通过使用能够形成稳定碳正离子的醇来实施的(见方案,TFA =三氟乙酸)。
  • Enantioselective Organocatalytic α-Alkylation of Ketones by SN1-Type Reaction of Alcohols
    作者:Maria Trifonidou、Christoforos G. Kokotos
    DOI:10.1002/ejoc.201101509
    日期:2012.3
    The enantioselective α-alkylation reaction of cyclic ketones is described. Our catalyst, based on a “privileged” pyrrolidine ring bearing a chiral thioxotetrahydropyrimidinone ring, is a highly reactive catalyst for cyclic ketones. When this catalyst was coupled with in situ generated carbocations derived from alcohols, the corresponding α-alkylated adducts were obtained in moderate to quantitative
    描述了环酮的对映选择性α-烷基化反应。我们的催化剂基于带有手性硫代四氢嘧啶酮环的“特权”吡咯烷环,是一种高反应性的环酮催化剂。当这种催化剂与原位生成的由醇衍生的碳阳离子偶联时,相应的 α-烷基化加合物以中等到定量的产率和低到高的对映选择性(高达 80% ee)获得。催化剂负载量可有效降低至 10%,这是文献中报道的此类有机催化转化的最低值。
  • Cooperative Organocatalysis for the Asymmetric γ Alkylation of α-Branched Enals
    作者:Giulia Bergonzini、Silvia Vera、Paolo Melchiorre
    DOI:10.1002/anie.201004761
    日期:2010.12.10
    α Branched leads to γ: The direct and enantioselective γalkylation of α‐substituted α,β‐unsaturated aldehydes under dienamine catalysis has been achieved. A cooperative catalysis system that involves dienamine activation of α‐branched enals and chiral Brønsted acid catalysis promotes an SN1‐alkylation pathway while ensuring complete γ‐site selectivity and high stereocontrol (see scheme; Bn=benzyl)
    α分支导致γ:在二烯胺催化下,实现了α-取代的α,β-不饱和醛的直接和对映选择性γ烷基化。一个合作的催化系统涉及α-支链烯类的二烯胺活化和手性布朗斯台德酸催化,可促进S N 1烷基化途径,同时确保完全的γ位选择性和高度立体控制(参见方案; Bn =苄基)。
  • Enantioselective Tandem Reactions at Elevated Temperatures: One-Pot Hydroformylation/SN1 Alkylation
    作者:Julian Stiller、Andreas J. Vorholt、Karoline A. Ostrowski、Arno Behr、Mathias Christmann
    DOI:10.1002/chem.201200639
    日期:2012.7.27
    Canned heat: The optimization of a tandem sequence of a metal‐catalyzed and a subsequent organocatalytic reaction is described (see figure). The tandem sequence was initially optimized toward a high yield by variations of substrate ratio, rhodium precursor, and ligands. The tandem reaction is also extendable to more complex alkenes and to substrates with additional functional groups.
    罐装热:描述了金属催化串联反应和随后的有机催化反应的优化过程(见图)。通过改变底物比例,铑前体和配体,最初将串联序列朝着高收率的方向进行了优化。串联反应也可扩展至更复杂的烯烃和具有其他官能团的底物。
  • The versatile roles of ammonium salt catalysts in enantioselective reduction and alkylation of α,β-unsaturated aldehydes: iminium catalysis, enamine catalysis and acid catalysis
    作者:Shi-Kai Xiang、Bo Zhang、Li-He Zhang、Yuxin Cui、Ning Jiao
    DOI:10.1039/c1cc10124b
    日期:——
    A novel strategy for highly efficient utilization of chiral ammonium salt catalysts has been described in this paper. Three kinds of catalytic functions including iminium catalysis, enamine catalysis, and acid catalysis of chiral ammonium salt catalysts, have been achieved in the enantioselective reduction and alkylation reaction of alpha,beta-unsaturated aldehydes with alcohols.
