  application, the selective deuterium labeling of these structures is restricted due to their electron-deficient properties. This study presents two comprehensive strategies for the deuteration of aromatic sulfones. The base-promoted deuteration uses DMSO-d6 as the deuterium source, resulting in a rapid H/D exchange within 2 h. Meanwhile, a silver-catalyzed protocol offers a much milder option by using economical

  芳香族砜是制药和材料科学中流行的支架。然而，与它们的广泛应用相比，这些结构的选择性氘标记由于其缺电子特性而受到限制。本研究提出了两种芳香族砜氘化的综合策略。碱促进氘化使用DMSO -d 6作为氘源，导致2小时内快速H/D交换。同时，银催化方案通过使用经济的 D 2 O 来提供标记的砜，从而提供了更温和的选择。

  substituents in the pyrrole ring. Diarylpyrrole 1 is a very potent (COX-2, IC50 = 60 nm) and selective (COX-1/COX-2 = > 1700) inhibitor whereas the isomeric 2 is completely inactive against COX-2. Modifications of the substituents on the fluorophenyl ring in 1 yields very potent inhibitors of COX-2 (IC50 = 40-80 nm) with excellent selectivity (1200 to > 2500) vs COX-1.
