Cyclic phosphonium anhydrides generated from bis-phosphine oxides and trifluoromethanesulfonic anhydride are shown as general coupling reagents in a dehydrative glycosylation reaction of C1-hemiacetals. This reaction protocol is characterized by a broad substrate scope and high yields, including reactions of O-, C-, N-, and S-based nucleophiles with furanose, pyranose, and deoxysugar donors.
reaction comprises two chronological meticulously-designed catalytic cycles: 1) rhodium-catalyzed formation of sulfonium ylide; 2) Brønsted acid-catalyzed formation of sulfoniumion. This protocol highlight-ed an effective and robust tactic to prepare glycosylsulfoniumion from glycosylsulfonium ylide precursor amenable for glycosylation.
