Two-step conversions of myo-inositol into (±)-2,3,4,5,6- and 1,3,4,5,6-penta-O-benzyl-myo-inositols are described. Starting from these monohydroxy derivatives of myo-inositol, O-β-L-arabinopyranosyl-(1 → 2)-sn-myo-inositol from Japanese green tea [SENCHA], Camellia sinensis, and O-α-D-galactopyranosyl-(1 → 3)-sn-myo-inositol (galactinol) as well as its homolog, O-α-D-galactopyranosyl-(1 → 6II)-galactinol, were synthesized by way of the in situ activating glycosylation procedure.
