• Direct Synthesis of 5-Aryl Barbituric Acids by Rhodium(II)-Catalyzed Reactions of Arenes with Diazo Compounds
  作者：Daniel Best、David J. Burns、Hon Wai Lam

  DOI：10.1002/anie.201502324

  日期：2015.6.15

  A commercially available rhodium(II) complex catalyzes the direct arylation of 5‐diazobarbituric acids with arenes, allowing straightforward access to 5‐aryl barbituric acids. Free NH groups are tolerated on the barbituric acid, with no complications arising from NH insertion processes. This method was applied to the concise synthesis of a potent matrix metalloproteinase (MMP) inhibitor.
