thermore, the novel combined use of Bu 2 SnCl 2− 2AgClO 4 was found to show promise as an
effective promoter of the glycosyl fluoride [66].
Me 2 GaCl and Me 2 GaOTf were introduced as new promoters of the glycosyl fluorides by
Kobayashi due to their strong affinity for fluoride. In this study, it was found that the
readily available Me 2 GaCl was more effective for the glycosylation reactions of glycosyl
fluorides ( > Scheme 29) [67].
