Abstract-Apple polyphenols (AP), which contain procyanidins as major components, have been reported to display potent antioxidant activity and several beneficial health effects. To investigate the protective effect of AP intake against murine cardiomyopathy caused by endogenous oxidative stress, we orally administered AP to heart/muscle-specific manganesesuperoxide dismutase (
We report a facile synthesis of triarylsulfonium triflates by selective aryl transfer from readily available mesityl iodonium(III) salts to diarylsulfides in the presence of a copper catalyst. The advantage of our protocol is that the iodonium(III) salts bearing a mesitylene (Mes) auxiliary efficiently promote selective S-arylation of diarylsulfides to produce the desired triarylsulfonium triflates without the formation of Mes-derived byproduct salts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
