Abstract/OtherAbstract:
The 3,5-dimethylphenylcarbamates of cellulose and amylose bearing a small amount of 3-(triethoxysilyl)propyl residues were synthesized by a simple process and efficiently immobilized onto a silica gel support by intermolecular polycondensation of the triethoxysilyl groups. The obtained chiral packing materials (CPMs) were evaluated by high-performance liquid chromatography. The polysaccharide derivatives containing about 1-2% of the 3-(triethoxysilyl)propyl residue were efficiently immobilized with a high chiral recognition. The immobilized CPMs could be used with the eluents containing chloroform and tetrahydrofuran, which cannot be used with the conventional coated-type CPMs. By using these eluents, the chiral recognitions for many racemates could be improved.
