additional information methyl D-allopyrano-sides are glucosylated primarily at position 6, yielding methyl alpha-D-glucopyranosyl-(1,6)-D-allopyranosides. The latter subsequently gave rise to methyl alpha-D-glucopyranosyl-(1,6)-alpha-D-glucopyranosyl-(1,6)-D-allopyranosides. The methyl alpha-D-hexopyranosides are better acceptors than the corresponding beta-glycosides Leuconostoc mesenteroides ?
