  使用三齿氨基苯酚 ONO 配体选择性 Suzuki-Miyaura 偶联保护硼酸

  摘要：

  硼酸保护基化学有力地增强了铃木-宫浦交叉偶联的多功能性。突出的例子包括三氟硼酸盐、N-甲基亚氨基二乙酸 (MIDA) 硼酸盐和 1,8-二氨基萘硼酰胺。在这项工作中，我们提出了一种双（2-羟基苄基）甲胺 (BOMA) 配体，它与硼酸形成三齿络合物，就像 MIDA 配体一样，但有机酸促进了脱保护。BOMA 硼酸盐在碱和酸水溶液中均表现出相当大的稳定性，并且对这些硼酸盐进行了多种化学选择性反应，包括选择性 Suzuki-Miyaura 偶联、钯催化硼化、酯水解、烷基化、锂化-硼化和氧化羟基脱硼。

  Non‐activated alkyl electrophiles, including alkyl iodides, bromides, tosylates, mesylates, and even chlorides, underwent copper‐catalyzed cross‐coupling with aryl boron compounds and alkyl 9‐BBN reagents (see scheme; 9‐BBN=9‐borabicyclo[3.3.1]nonane). The reactions proceed with practically useful reactivities and thus complement palladium‐ and nickel‐catalyzed Suzuki–Miyaura coupling reactions of alkyl halides

  Article describes the development of a base-free, nickel-catalyzed decarbonylative coupling of carboxylic acid fluorides with diboron reagents to selectively afford aryl boronate ester products. Detailed studies were conducted to assess the relative rates of direct transmetalation between aryl boronate esters and diboron reagents and a bisphosphine nickel(aryl)(fluoride) intermediate. These investigations

  作者：Connor P. Delaney、Vincent M. Kassel、Scott E. Denmark

  DOI：10.1021/acscatal.9b04353

  日期：2020.1.3

  Herein, a mild and operationally simple method for the Suzuki−Miyaura cross-coupling of boronic esters is described. Central to this advance is the use of the organic-soluble base, potassium trimethylsilanolate, which allows for a homogeneous, anhydrous cross-coupling. The coupling proceeds at a rapid rate, often furnishing products in quantitative yield in less than 5 min. By applying this method
