  Protodeboronation of ortho- and para-Phenol Boronic Acids and Application to ortho and meta Functionalization of Phenols Using Boronic Acids as Blocking and Directing Groups

  摘要：

  The first metal-free thermal protodeboronation of ortho- and para-phenol boronic acids in DMSO was developed. The protodeboronation was successfully applied to the synthesis of ortho- and meta-functionalized phenols using the boronic acid moiety as a blocking group and a directing group, respectively. Mechanistic studies suggested that this protodeboronation proceeds through the coordination of water to the boron atom followed by sigma-bond metathesis.

• One-Pot Generation of Functionalized Benzynes from Readily Available 2-Hydroxyphenylboronic Acids
  作者：Takashi Ikawa、JingKai Sun、Akira Takagi、Shuji Akai

  DOI：10.1021/acs.joc.9b03169

  日期：2020.3.6

  We developed a one-pot method for the generation of benzynes from a range of readily available 2-hydroxyphenylboronic acids. This method features the in situ activation of both boronic acid and hydroxyl groups of the substrate to enhance benzyne generation at 60 °C. Such mild conditions facilitate the generation of functionalized benzynes that immediately react with diverse arynophiles to produce multisubstituted

  我们开发了一种一锅法，可从一系列容易获得的2-羟基苯基硼酸中生成苯炔。该方法的特点是原位活化硼酸和底物的羟基，以增强60°C下苯并炔的生成。这种温和的条件促进了官能化的苯并炔的生成，该苯并炔立即与各种亲核体反应生成多取代的稠合苯。

  A protocol for C−H carboxylation of electron‐deficient 2‐pyridylphenols with CO2 through a Rh(II)‐catalyzed C−H bond activation under redox‐neutral conditions has been developed. A suitable phosphine ligand was crucial for this reaction. This method provided, in generally high yields, an access to a class of pyrido‐coumarins that are key structural motifs in biologically important molecules. Facile
