In a simple and efficient two-step reaction, the 2,3- and 4,6-di-O- hydroxypropyl regioselectively-functionalized glucose derivatives, 5, 12 and 13 were synthesized by reaction of the allyl 4,6-O-benzylidene-β-D- glucopyranoside (1), allyl 2,3-di-O-benzyl

Treatment of α,α′-dibromo-m-xylylene with 6-O-unprotected thiomaltoside 4 as glycosyl donor (→ 5), followed by 4-O-unprotected galactoside derivative 6 as acceptor, afforded β-linked macrocyclic trisaccharide 9β in high yield after removal of the 3-O-MPM protective group and subsequent intramolecular glycoside bond formation. Similarly, by the same sequence of steps, the corresponding tetrasaccharide 14β was obtained from 5 and 4b-O-unprotected lactoside 11. For reiterative glycoside bond formation, treatment of α,α′-dibromo-m-xylylene with 3-O-unprotected thioglycoside 15 as donor (→ 16), followed by 4,6-O-unprotected glucoside, and subsequent glycosylation afforded macrocyclic maltotrioside 22, which was transformed into known maltotrioside 23. A sight modification of the protecting-group pattern in maltotrioside synthesis resulted in generally higher yields in the ligation of the building blocks to the m-xylylene spacer, particularly in the second glycosylation step, thus providing macrocyclic maltotrioside 40α, which was transformed into known maltotriosides 41α and 41β.
