    双功能金鸡纳生物碱催化:用于直接创建非相邻立体中心的催化不对称串联共轭加成 - 质子化
    摘要:
    催化串联不对称反应构成了直接从非手性前体在非环状分子中不对称构建非相邻立体中心的有力策略。在这篇通讯中,我们报告了在双功能金鸡纳生物碱催化剂的催化下,三取代的碳供体对 2-氯丙烯腈的高度对映选择性和非对映选择性加成。这代表了第一个不对称串联共轭加成-质子化,对两个不相邻的立体中心进行有效的催化控制。正如 (-)-manzacin A 的简洁且高度立体选择性的正式全合成所证明的那样,这种不对称串联反应为 1,3-叔-四元立体中心的对映选择性和非对映选择性创建建立了一种新的通用催化方法。

  • Catalytic Asymmetric Alkylation Reactions for the Construction of Protected Ethylene-Amino and Propylene-Amino Motifs Attached to Quaternary Stereocentres
    作者:Thomas A. Moss、David M. Barber、Andrew F. Kyle、Darren J. Dixon

    日期:2013.2.25
    An efficient catalytic and stereoselective method for the direct construction of protected ethylene‐amino and propylene‐amino scaffolds attached to quaternary stereocentres is reported. Preliminary investigations revealed a mild base catalysed nucleophilic ring opening of N‐sulfonyl aziridines using the commercially available phosphazene base 2‐tert‐butylimino‐2‐diethylamino‐1,3‐dimethyl‐perhydro‐1
    据报道,一种有效的催化和立体选择性方法可直接构建连接到季立体中心的受保护的乙烯-基和丙烯-基骨架。初步研究表明,使用市售的腈碱2-叔丁基亚基-2-二乙基-1,3-二甲基-过-1,3,2-二(BEMP)可以催化N-磺酰基氮丙啶的轻度碱催化亲核开环。可能并导致与多种次甲基碳酸进行高效烷基化反应。可以使该反应高度不对称(ee高达97%),通过采用相转移催化来控制立体感应。将烷基取代基并入氮丙啶亲电子试剂中,导致该方法具有极高的非对映选择性(高达30:1 dr)。使用N保护的环氨基磺酸盐作为亲电子试剂的进一步扩展成功实现了一系列亲核试剂(高达96%ee和45:1 dr)并允许一系列保护基团(氨基甲酸,磺酰基,膦酰基,苄基) )并结合到烷基化加合物中。最后,在有用的杂环和带有天然产物结构成分的化合物的合成中证明了产物的实用性。

  • An oxidative coupling for the synthesis of arylated quaternary stereocentres and its application in the total synthesis of powelline and buphanidrine
    作者:Katherine M. Bogle、David J. Hirst、Darren J. Dixon
    DOI:10.1016/j.tet.2010.04.132
    日期:2010.8
    Catechol derivatives directly bonded to all-carbon quaternary stereocentres are prevalent in nature. An oxidative coupling strategy for the synthesis of this motif is described. Pivoting on the base-catalysed Michael addition of carbon-centred pro-nucleophiles to in situ generated ortho-benzoquinones, the method is broad in scope, high yielding and provides remarkably simple access to this challenging motif. The application of this methodology in the total synthesis of the crinane-type amaryllidaceae alkaloids (+/-)-powelline and (+/-)-buphanidrine is demonstrated and our efforts towards an enantioselective synthesis described.

  • An Organocatalytic Oxidative Coupling Strategy for the Direct Synthesis of Arylated Quaternary Stereogenic Centers
    作者:Katherine M. Bogle、David J. Hirst、Darren J. Dixon
    DOI:10.1021/ol702277v
    日期:2007.11.1
    A broadly applicable oxidative coupling strategy of 3-substituted catechols and carbon-centered pro-nucleophiles for the construction of arylated quaternary stereogenic centers has been developed. Pivoting on a base-catalyzed addition of a carbon-centered acid to an in situ generated o-benzoquinone, the method is general and atom-economical and provides remarkably efficient access to one of the most challenging structural motifs. Furthermore, use of chiral bifunctional organocatalysts allows the process to be rendered asymmetric (up to 81% ee).
