254ChemInform Abstract Using the refluxing two-phase system Et3N•HF/CCl4 or the homogeneous system HF/MeNO2, the preparation of anomerically pure glycosyl fluorides such as (II) or (IV) is achieved avoiding the use of expensive AgF, the long reaction times of KHF2 and the laborious drying methods for water-soluble solvents such as MeCN.
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.
