  • Direct and highly regioselective and enantioselective allylation of β-diketones
    作者:Wesley A. Chalifoux、Samuel K. Reznik、James L. Leighton
    DOI:10.1038/nature11189
    日期:2012.7
    A simple, regioselective and enantioselective method for allylating β-diketones has been developed, significantly expanding the pool of easily accessible enantiomerically enriched and functionally complex tertiary carbinols. The enantioselective allylation of ketones represents a problem of fundamental importance in asymmetric reaction design, especially given that only a very small number of methods can generate tertiary carbinols. In this manuscript, the authors describe a simple, regioselective and enantioselective method for allylating β-diketones. This reaction significantly expands the pool of enantiomerically enriched and functionally complex tertiary carbinols that can be easily accessed and also overturns more than a century of received wisdom regarding the reactivity of β-diketones. The enantioselective allylation of ketones is a problem of fundamental importance in asymmetric reaction design, especially given that only a very small number of methods can generate tertiary carbinols. Despite the vast amount of attention that synthetic chemists have given to this problem1,2,3,4,5,6,7,8, success has generally been limited to just a few simple ketone types. A method for the selective allylation of functionally complex ketones would greatly increase the utility of ketone allylation methods in the chemical synthesis of important targets. Here we describe the operationally simple, direct, regioselective and enantioselective allylation of β-diketones. The strong tendency of β-diketones to act as nucleophilic species was overcome by using their enol form to provide the necessary Brønsted-acid activation. This reaction significantly expands the pool of enantiomerically enriched and functionally complex tertiary carbinols that may be easily accessed. It also overturns more than a century of received wisdom regarding the reactivity of β-diketones.
    一种简单的、区域选择性和对映选择性的烯丙基化β-二酮方法已被开发出来,显着扩大了易于获得的对映体丰富且功能复杂的叔醇的库。酮的对映选择性烯丙基化是不对称反应设计中的一个非常重要的问题,特别是考虑到只有极少数的方法可以生成叔醇。在这篇手稿中,作者描述了一种简单的区域选择性和对映选择性烯丙基化 β-二酮的方法。该反应显着扩大了对映异构体丰富且功能复杂的叔醇库,这些叔醇可以很容易地获得,并且还颠覆了一个多世纪以来关于β-二酮反应性的公认观点。酮的对映选择性烯丙基化是不对称反应设计中一个非常重要的问题,特别是考虑到只有极少数的方法可以生成叔醇。尽管合成化学家对这个问题给予了大量的关注1,2,3,4,5,6,7,8,但成功通常仅限于几种简单的酮类型。功能复杂酮的选择性烯丙基化方法将大大增加酮烯丙基化方法在重要靶标化学合成中的效用。在这里,我们描述了操作简单、直接、区域选择性和对映选择性的β-二酮烯丙基化。通过使用烯醇形式提供必要的布朗斯台德酸活化,克服了β-二酮作为亲核物质的强烈倾向。该反应显着扩大了对映体富集且功能复杂的叔醇库,并且可以很容易地获得。它还颠覆了一个多世纪以来关于β-二酮反应性的公认观点。

    日期:2010.4
    A method to prepare a variety of substituted 3-acyl-5-hydroxybenzofurans efficiently that relies on copper(II) triflate-catalyzed cycloaddition of unactivated 1,4-benzoquinones with 1,3-dicarbonyl compounds is reported. The reaction was shown to be operationally straightforward and proceeds expediently under mild conditions to give the corresponding products in good to excellent yields (up to 95%) and with complete regioselectivity.
