  瞬态亚胺作为苯甲醛的无金属邻-C-H硼化反应的指导基团

  摘要：

  Organoboron试剂是重要的合成中间体，在合成有机化学中具有广泛的应用。当前使用的选择性硼化策略很大程度上依赖于过渡金属催化剂的使用。因此，非常需要确定更温和的无过渡金属硼化条件。我们在本文中提出了一种统一的策略，该方法使用一种简单的无金属方法，利用一个亚胺瞬态导向基团，对缺电子的苯甲醛衍生物进行选择性C–H硼化。该策略涵盖了广泛的反应，并且（i）即使是高度空间位阻的C–H键也可以顺利地被硼化，（ii）尽管存在其他潜在的导向基团，但该反应还是选择性地在o处发生。苯甲醛部分的-C–H键，以及（iii）附加到苯甲醛衍生物上的天然产物也可以产生适当的硼化产物。此外，该方案的有效性通过以下事实得以证实：即使在一系列外部杂质的存在下，反应也会进行。

  BSIH ((E)-N′-(2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzylidene)isonicotinohydrazide) is a prodrug version of the metal chelator SIH ((E)-N′-(2-hydroxybenzylidene)isonicotinohydrazide) in which a boronate group prevents metal chelation until reaction with hydrogen peroxide releases SIH, which is then available for sequestering iron(III) and inhibiting iron-catalyzed oxidative damage.

  to prepare aryl and heteroaryl iodides by sequential C–H borylation and iodination is reported. The regioselectivity of this process is controlled by steric effects on the C–H borylation step and is complementary to existing methods to form aryl iodides. The iodination of boronic esters has potential for the synthesis of radiolabeled aryl iodides, as demonstrated by the concise synthesis of a potential

A number of late-stage C–H functionalization have been described using the same catalysts. Furthermore, we show that one of the catalysts could be used even in open air for the C(sp2)–H and C(sp3)–H borylations enabling the method more general

  在这里，我们描述了一类新的 C-H 硼化催化剂的发现及其在芳族、杂芳族和脂肪族系统的区域选择性 C-H 硼化中的应用。新催化剂具有 Ir-C(噻吩基) 或 Ir-C(呋喃基) 阴离子配体，而不是标准 C-H 硼化条件中使用的二胺型中性螯合配体。据报道，这些新发现的催化剂的使用对不同种类的芳烃底物显示出优异的反应性和邻位选择性，并具有高分离产率。此外，该催化剂被证明对大量脂肪族底物的选择性 C(sp 3)–H 键硼化。杂环分子利用 C-H 键固有的高反应性选择性地硼化。已经使用相同的催化剂描述了许多后期 C-H 功能化。此外，我们表明其中一种催化剂甚至可以在露天用于 C(sp 2 )-H 和 C(sp 3 )-H 硼酸化，从而使该方法更加通用。初步的机理研究表明，活性催化中间体是 Ir(bis)boryl 络合物，连接的配体作为双齿配体。总的来说，这项研究强调了新型 C-H 硼酸化催化剂的发现，这些催化剂应该在
