Efficient Glycosylation Using In(OTf)<sub>3</sub> as a Lewis Acid: Activation of <i>N</i>-Phenyltrifluoroacetimidate or Thioglycosides with Halogenated Reagents or PhIO
Access this Article
In(OTf)<sub>3</sub> efficiently activated <i>N</i>-phenyltrifluoroacetimidate and In(OTf)<sub>3</sub> in combination with various halogenated reagents or PhIO promoted glycosylation using thioglycoside in good yields. The combination with iodine interhalogens (e.g., ICl or IBr) effectively promoted α-sialylation.
