The asymmetric synthesis of novel, potent phosphoramidate alpha(2-6)sialyltransferase transition-state analogue inhibitors such as (R)-9 (K-i - 68 muM) is described, via condensation of cytidine phosphitamide 6 with key chiral, non-racemic alpha-aminophosphonates, prepared in > 98 % ee by Mitsunobu azidation followed by Staudinger reduction of the corresponding chiral, non-racemic alpha-hydroxyphosphonates.
