    Suzuki−Miyaura Cross-Coupling of Potassium Trifluoroboratohomoenolates
    摘要:
    Ketone-, ester-, and amide-containing potassium trifluoroboratohomoenolates were prepared in good to excellent yields from the corresponding unsaturated carbonyl compounds. They were shown to be effective coupling partners in the Suzuki-Miyaura reaction with a variety of electrophiles including electron-rich and electron-poor aryl bromides and -chlorides.

  • Building Functionality through Sequential CB and CF Bond Formation
    作者:Gerard Palau-Lluch、Elena Fernández

    日期:2013.5.17
    α′‐Fluoro β‐boryl ketones can be efficiently synthesised from a sequential organocatalytic β‐boration pathway and consecutive electrophilic fluorination reaction in an acidic medium. Alternatively, the regioisomers of α‐fluoro β‐boryl ketones can be diastereoselectively obtained from Cu(I)‐mediated β‐boration followed by in situ fluorination of the boron enolate. Enantioenriched mixtures of the major

    The Cu‐catalyzed, one‐pot tandem (asymmetric) borylation of β‐chloroalkyl aryl ketones via the in situ generated acyclic enones with bis(pinacolato)diboron was achieved efficiently to reach up to 97 % yield and 99 % enantioselectivity for the formal sp3 CCl borylation products. The present methodology provides an efficient alternative route to (chiral) alkylboron compounds.

The present nickel-catalyzed reaction is complementary to the iridium-catalyzed transposition reported by Murakami leading to the corresponding anti-homoallylic alcohols.

    (LMCT) process. These reactions exhibit remarkably broad substrate scope (>150 examples in total), and most importantly, all of these three reactions show unconventional regioselectivity, with the occurrence of C(sp3)–H borylation, thiolation, and sulfinylation preferentially at the distal methyl position. The procedures are operationally simple and readily scalable and provide access to high-value products
    催化 C(sp 3 )–H 功能化为构建有机分子提供了巨大机会,促进了复杂药物化合物的衍生化。在此框架内,直接氢原子转移 (HAT) 光催化成为实现这一目标的一种有吸引力的方法。然而,这些方案中使用的可行底物是有限的,并且位点选择性显示出对活化和热力学有利的 C(sp 3 )–H 键的偏好。在此,我们描述了无向铁催化 C(sp 3)–H 硼酸化、硫醇化和亚磺酰化反应由光诱导配体到金属电荷转移 (LMCT) 过程实现。这些反应表现出非常广泛的底物范围(总共 > 150 个例子),最重要的是,所有这三个反应都表现出非常规的区域选择性,C(sp 3 )–H 硼酸化、硫醇化和亚磺酰化优先发生在远端甲基位置。这些程序操作简单,易于扩展,一步即可从简单的碳氢化合物中获取高价值产品。机理研究和对照实验表明,所提供的位点选择性不仅与 HAT 物种相关,而且在很大程度上受到硼基和砜基自由基受体的使用的影响。
  • Structure and Reactivity of a Preactivated sp<sup>2</sup>–sp<sup>3</sup> Diboron Reagent: Catalytic Regioselective Boration of α,β-Unsaturated Conjugated Compounds
    作者:Ming Gao、Steven B. Thorpe、Christian Kleeberg、Carla Slebodnick、Todd B. Marder、Webster L. Santos
    DOI:10.1021/jo2003488
    日期:2011.5.20
    A novel sp(2)-sp(3) diboron reagent has been developed for the copper-catalyzed beta-boration of alpha,beta-unsaturated conjugated compounds. The reaction proceeds under mild conditions with various substrates, i.e., alpha,beta-unsaturated esters, ketones, nitriles, ynones, amides, and aldehydes, in the absence of additives such as phosphine and sodium tert-butoxide to provide beta-borylhomoenolates in good to excellent yields. The presence of an sp(3)-hybridized boron center, un-ambigously confirmed by X-ray crystallography, sufficiently activates the unsymmetrical pinacolato diisopropanolaminato diboron (PDIPA diboron, 2) to transfer the sp(2)-hybridized boron moiety chemoselectively. These observations suggest that the activation of one of the boron atoms is an essential step in the Cu-catalyzed beta-boration catalytic cycle.
