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 NH groups are tolerated on the barbituric acid, with no complications arising from NH insertion processes. This method was applied to the concise synthesis of a potent matrix metalloproteinase (MMP) inhibitor.
the unbalanced or culminated expression of matrix metalloproteinases (MMPs). The molecularimaging of locally upregulated MMP activity in vivo is a clinical challenge. Actually, radioligands based on nonpeptidyl MMP inhibitors (MMPIs) are currently in development as putative radiopharmaceutical agents for the noninvasive in vivo assessment of activated MMPs. Nonpeptidyl MMPIs bind to the zinc active
