Convergent and convenient totalsynthesis of branched hepta-β-glucoside 1 having phytoalexin-elicitor activity was efficiently accomplished by way of two one-pot sequential glycosylation reactions. Trisaccharide 8 was synthesized in high yield by TfOH-catalyzed one-pot glycosylation using three component monosaccharides and subsequent selective deprotection of a 6′-O-TBDPS group. The second one-pot
