Article abstract of DOI:10.1246/cl.1982.1383

Dehydrative glycosylation of benzyl 2,3,4-tri-O-benzyl α-D-glucopyranoside with hepta-O-benzyl-kojibiose, -sophorose, -nigerose, -laminaribiose, -maltose, -cellobiose, -isomaltose, and -gentiobiose gave 16 linear trisaccharide derivatives.The reaction of α(1->2)-, β(1->3)-, α(1->4)-, and β(1->6)-linked biose derivatives shows the α-selectivity, while the reaction of the others does the β-selectivity.
