Thus, alkyne functionalized diruthenium compounds 6 and 7 were reacted with glucose derivative 10 presenting an azide group directly anchored to the glucopyranosyl ring (Scheme 6). Amide conjugate 20 was isolated in good yield (72%), while difficulties were encountered in the purification of ester analogue 19 which was recovered in poorer yield (28%). All compounds were fully characterized by 1 H, 13 C nuclear magnetic resonance (NMR) spectroscopy, high resolution electrospray ionization mass spectrometry (HR ESI-MS) and elemental analysis (see the Experimental Section Chemistry in Supporting Information for full details). Mass spectrometry corroborated the spectroscopic data with the trithiolato diruthenium glucose and galactose conjugates 19-26 showing molecular ion peaks corresponding to [M-Cl] + ions.
