Polymerizable Methacrylate Carbohydrate Derivatives: 1,2:3,4-Di-O-isopropylidene-6-O-methacryloyl-[alpha]-D-galactopyranose and 1,2:5,6-Di-O-isopropylidene-3-O-methacryloyl-[alpha]-D-glucofuranose

The structures, both C₁₆H₂₄O₇, have been determined to investigate the possibility of using these carbohydrate-containing monomers or related compounds for solid-state polymerization. The orientation of the methacrylate groups in the galactose derivative is suitable for solid-state reaction but the distance between the potentially reacting vinyl carbons is too great, 5.065 (5) Å, for a facile reaction. The glucose derivative is disordered, with one of the isopropylidene rings assuming two different envelope conformations in the crystal. In the glucose derivative there are no approaches of the appropriate vinyl group atoms closer than 6.439 (3) Å.
