  Efficient synthesis of halohydroxypyridines by hydroxydeboronation

  摘要：

  This paper describes a general method for the synthesis of halohydroxypyridines from novel halopyridinylboronic acids and esters recently described by some of us. Halopyridinylboronic acids and esters have been efficiently hydroxydeboronated under mild conditions by employing hydrogen peroxide or meta-chloroperbenzoic acid. These hydroxylations take place regioselectively, without other oxidation (N-oxide formation). (C) 2004 Elsevier Ltd. All rights reserved.

• METHODS FOR FORMING SATURATED (HETERO)CYCLIC BORYLATED HYDROCARBONS AND RELATED COMPOUNDS
  申请人：BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITY

  The disclosure relates to methods for forming at least partially saturated cyclic and heterocyclic borylated hydrocarbons, as well as related compounds, which can be precursor compounds in the synthesis of any of a variety of pharmaceutical or medicinal compounds with a desired structure and/or stereochemistry for drug synthesis or drug candidate evaluation. The methods generally include reduction of an unsaturated cyclic or heterocyclic borylated hydrocarbon having a boron-containing substituent at an sp 2 -carbon, where such reduction converts the sp 2 -carbon to an sp 3 -carbon at the point of attachment of the boron-containing substituent. The methods can exhibit a selectivity for syn-addition during reduction, which can provide stereospecific products, such as when the unsaturated cyclic or heterocyclic reactant is multiply substituted with boron groups and/or other functional groups.

  本发明涉及用于形成至少部分饱和的环状和杂环硼化烃的方法，以及相关的化合物，这些化合物可以是合成多种具有所需结构和/或立体化学的药物或药用化合物的前体化合物。这些方法通常包括将具有sp2碳上含硼取代基的不饱和环状或杂环硼化烃还原，这样的还原将sp2碳转化为与含硼取代基连接点上的sp3碳。这些方法在还原过程中可表现出对顺式加成的选择性，从而可以提供立体特异性产物，例如当不饱和环状或杂环反应物上多元取代硼基团和/或其他功能基团时。

  Herein, we disclose a RhIII-catalyzed heteroarylation of C(sp3)–H and C(sp2)–H bonds in heterocycles with organoboron reagents. This protocol displays high efficiency and excellent functional group tolerance. A range of heterocyclic boronates with strong coordinating atoms, including pyridine, pyrimidine, pyrazole, thiophene, and furan derivatives, can be extensively served as the coupling reagents

  However, the development of Wee1 inhibitors faces some challenges. AZD1775, the first-in-class Wee1 inhibitor, has poor kinase selectivity and dose-limiting toxicity. Here, we report the discovery of 12h, a highly selective and potent Wee1 inhibitor with a favorable pharmacokinetic profile. 12h showed strong antiproliferative effects against Lovo cells, a colorectal cancer cell line, both in vitro and
