A short route to phenyl 1-thio-β-maltotrioside derived building blocks and their use for the synthesis of the branched nonasaccharide, 6'''-α-maltotriosyl-maltohexaose, is described. Instead of using glucose and maltose as starting materials, maltotriose was used and synthetically manipulated in a well designed strategy to obtain phenyl O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl)-(1→4)-O-(2,3,6-
