The enantiomeric synthesis and profiling of sulfoxide-based rofecoxib and etoricoxib (Merck) prodrugs are reported. The preparation of the sulfoxide analogues 2 and 4, and their enantiomeric pure forms is discussed as well as their potential to act as prodrugs to the potent and selective sulfone-con...
