- Transition metal-free direct C–H trifluoromethyltion of (hetero)arenes with Togni's reagent
-
A new transition-metal-free direct C–H trifluoromethylation reaction of (hetero)arenes with Togni's reagent was developed. This transformation proceeded smoothly under mild conditions and exhibited good tolerance of many synthetically relevant functional groups. It provided an alternative approach for the synthesis of trifluoromethylated (hetero)arenes.

- 2-heterosubstituted-3-(4-methylsulfonyl)phenyl-5-trifluoromethyl pyridines as selective and orally active cyclooxygenase-2 inhibitors
-
A series of novel 2-alkoxy, 2-thioalkoxy and 2-amino-3-(4- methylsulfonyl)phenylpyridines has been synthesized and shown to be highly potent and selective cyclooxygenase-2 (COX-2) inhibitors. Structure-activity relationship studies have demonstrated that central pyridine ring substituents play an important role in the COX-2 potency, selectivity vs the COX-1 enzyme, and oral activity.

- 2-pyridinyl-3(4-methylsulfonyl)phenylpyridines: Selective and orally active cyclooxygenase-2 inhibitors
-
A series of novel 2-pyridinyl-3-(4-methylsulfonyl)phenylpyridines has been synthesized and evaluated with respect to their ability to inhibit the isozymes of cyclooxygenase, COX-1, and COX-2. Optimum COX-2 activity is observed by introduction of a substituent at C5 of the central pyridine. 5- Chloro-3-(4-methylsulfonyl)phenyl-2(2-methyl-5-pyridinyl)pyridine 33 was identified as the optimum compound in this series.
