  Pyridone Methylsulfone Hydroxamate LpxC Inhibitors for the Treatment of Serious Gram-Negative Infections

  摘要：

  The synthesis and biological activity of a new series of LpxC inhibitors represented by pyridone methylsulfone hydroxamate 2a is presented. Members of this series have improved solubility and free fraction when compared to compounds in the previously described biphenyl methylsulfone hydroxamate series, and they maintain superior Gram-negative antibacterial activity to comparator agents.

  Methods for the selective borylation of arenes, including arenes substituted with an electron-withdrawing group (e.g., 1-chloro-3-fluoro-2-substituted benzenes) are provided. The methods can be used, in some embodiments, to efficiently and regioselectively prepare borylated arenes without the need for expensive cryogenic reaction conditions.
