Pyrimidin‐2‐yl sulfonates, as a reaction partner, can be easily prepared from inexpensive commercial materials and are efficiently cross‐coupled with arylboronic acids and terminal alkynes by using Pd(OAc)2‐catalyzed Suzuki and Sonogashira reactions. A wide array of C2‐functionalized pyrimidines have been prepared in good to excellent yields. 2‐Arylpyridines and 2‐(oct‐1‐ynyl)pyridine were also synthesized.
An efficient method for carbon-carbon bond formation is described. The process employs the palladium-catalyzed copper-mediated cross-coupling of diheteroaryl disulfides with arylboronic acids or alkynes to deliver C À C coupling products through unreactive C À S bond cleavage. The scope of the coupling reactions, including both the disulfides and arylboronic acids or alkynes, are documented.
Pyrimidin‐2‐yl sulfonates, as an efficient reaction partner, which can be easily prepared from cheap commercial materials, were coupled with phenols and anilines to give a wide array of C2‐aryloxy‐ and arylaminopyrimidines in good to excellent yields under mild reaction conditions.
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.
