Maltopentaose was immobilized on silica gel and used as a recyclable primer in the reaction of glycogen phosphorylase with D-glucal. An improved method to obtain 2-deoxy-α-D-arabino-hexopyranosyl phosphate (4) by using this catalyst as well as the specific synthesis of low molecular weight, water-soluble 2-deoxy-maltooligosaccharides (12, 13, 14 and 15) are described. Further investigations with modified phosphorylase substrates showed that mannosyl phosphate (16) can be slowly transferred to the primer maltotetraose. α-1,4-Mannosyl-maltotetraose (17) and its degradation product α-1,4-mannosyl-maltose (18) were identified.
