The treatment of the fully benzylated α-cyclodextrin with the hot compressed mixed solvent of dioxane/water (v/v=1/1) at 270 °C and 150 kg/cm2 for 40 min afforded 2,3,6-tri-O-benzyl-D-glucopyranose in good yield. The hydrothermolysis of the fully benzylated α-cyclodextrin at 240 °C produced partially benzylated maltooligosaccharide derivatives.
