  Gold-Catalyzed Proto- and Deuterodeboronation

  摘要：

  A mild gold-catalyzed protodeboronation reaction, which does not require acid or base additives and can be carried out in "green" solvents, is described. As a result, the reaction is very functional-group-tolerant, even to acid- and base-sensitive functional groups, and should allow for the boronic acid group to be used as an effective traceless directing or blocking group. The reaction has also been extended to deuterodeboronations for regiospecific ipso-deuterations of aryls and heteroaryls from the corresponding organoboronic acid. Based on density functional theory calculations, a mechanism is proposed that involves nucleophilic attack of water at boron followed by rate-limiting B-C bond cleavage and facile protonolysis of a Au-sigma-phenyl intermediate.

  transfer hydrogenation and borrowing hydrogen reactions paved the way to manipulate simple alcohols in previously unthinkable manners and circumvented the need for hydrogen gas. Analogously, transfer hydrocarbylation could greatly increase the versatility of tertiary alcohols. However, this reaction remains unexplored because of the challenges associated with the catalytic cleavage of unactivated C–C bonds

  转移氢化和借用氢反应的出现为以以前无法想象的方式操作简单的醇铺平了道路，并避免了对氢气的需求。类似地，转移烃基化可以大大提高叔醇的多功能性。然而，由于与未活化的CC键的催化裂解有关的挑战，该反应仍未得到探索。在本文中，我们报道了铑（I）催化的穿梭芳基化反应，通过氧化还原中性β-碳消除机制，在未应变的三芳基醇中裂解C（sp 2）-C（sp 3）键。使用良性醇作为潜在的C，实现了从叔醇到酮的取代（杂）芳基的选择性转移烃基化-亲核试剂。所有初步的机械实验都支持可逆的β-碳消除/迁移插入机制。在更广泛的背景下，这种新颖的反应性为催化叔醇的操作提供了新的平台。

• A new approach to silicon rhodamines by Suzuki–Miyaura coupling – scope and limitations
  作者：Thines Kanagasundaram、Antje Timmermann、Carsten S Kramer、Klaus Kopka

  DOI：10.3762/bjoc.15.250

  日期：——

  Background: Silicon rhodamines are of particular interest because of their advantageous dye properties (fluorescence- and biostability, quantum efficiency, tolerance to photobleaching). Therefore, silicon rhodamines find frequent application in STED (stimulated emission depletion) microscopy, as sensor molecules for, e.g., ions and as fluorophores for the optical imaging of tumors. Different strategies were already employed for their synthesis. Because of just three known literature examples in which Suzuki–Miyaura cross couplings gave access to silicon rhodamines in poor to moderate yields, we wanted to improve these first valuable experimental results.

  Results: The preparation of the xanthene triflate was enhanced and several boron sources were screened to find the optimal coupling partner. After optimization of the palladium catalyst, different substituted boroxines were assessed to explore the scope of the Pd-catalyzed cross-coupling reaction.

  Conclusions: A number of silicon rhodamines were synthesized under the optimized conditions in up to 91% yield without the necessity of HPLC purification. Moreover, silicon rhodamines functionalized with free acid moieties are directly accessible in contrast to previously described methods.

  背景：硅罗丹明因其有利的染料特性（荧光和生物稳定性、量子效率、对光漂白的耐受性）而特别受到关注。因此，硅罗丹明常用于STED（受激发射耗尽）显微镜，作为例如离子和肿瘤光学成像的荧光团的传感器分子。已经采用了不同的策略来合成它们。因为在仅有的三个已知文献实例中，铃木-宫浦交叉偶联以较差到中等产率得到了硅罗丹明，我们想要改进这些初步有价值的实验结果。 结果：提高了xanthene triflate的制备，并筛选了多种硼源以找到最佳的偶联伴侣。在优化了钯催化剂之后，评估了不同的取代硼氧烷来探索钯催化的交叉偶联反应的范围。 结论：在优化的条件下合成了多种硅罗丹明，产率高达91%，无需HPLC纯化。此外，与先前描述的方法相比，带有自由酸基团的功能化硅罗丹明可以直接获得。
