Synthesis of d-fructose conjugated ligands via C6 and C1 and their corresponding [Ru(bpy)(L)]Cl complexes.

A pyridyl triazole (pyta) modified sucrose ligand was prepared in a seven step synthesis using d-glucose as the protection group for d-fructose and starting from commercially available sucrose. After complexation with Ru(bpy)Cl precursor, the sucrose-conjugated Ru complex of the general formula [Ru(bpy)(L)]Cl was formed. Acidic cleavage of the d-glucose unit led to the first d-fructose conjugated metal complex viad-fructose C6 in literature.
