In this study, a SPhosAuNTf2-promoted DMF-modulated glycosylation approach was developed for the highly alpha-selective synthesis of various linkage types of alpha-glucans using glycosyl (Z)-ynenoates as donors. The substituent groups were found to play a significant role in the alpha-selective glucosylation reactions. The approach was effectively applied to the stereospecific synthesis of the alpha-1,6-linked triglucoside.
