In this work, we have developed synthetic routes for novel trifluorinated glucopyranose analogues using a Chiron approach. This strategy used inexpensive levoglucosan as a starting material, and we achieved a microwave glycosylation method as a key step. All analogues adopted standard 4 C 1 glucopyranose conformations, and a gauche−gauche conformation for the fluoromethyl group (C5−C6 linkage) was ascertained for congeners with a fluorine atom at C-6. Finally, the lipophilicity of trifluorinated glucose analogues was assessed with a log P determination method based on 19 F NMR spectroscopy.
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.
