Abstract

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)2Cl2 precursor, the sucrose-conjugated Ru complex of the general formula [Ru(bpy)2(L)]Cl2 was formed. Acidic cleavage of the D-glucose unit led to the first D-fructose conjugated metal complex via D-fructose C6 in literature. Additionally, pyta-modified D-fructose via C1 and the corresponding Ru complex were synthesized. All compounds were analyzed by Rfvalues, specific rotation, NMR, IR, UV/Vis and fluorescence spectroscopy, mass spectrometry and elemental analysis.
