A simple synthesis of deoxyuridine and uridine 5'-mono- and 5'-tri-phosphates, C-5 alkylated by glycosides of 2-acetamido-2-deoxy-β-D-glucopyranose and α-D-mannopyranose, is reported.The glycosides (5) and (7) have been obtained respectively, by condensation of 3,4,6-tri-O-acetyl-1,2-dideoxy-1,2-dihydro-2'-methyl-α-D-glucopyranosooxazole (2), and tetra-O-benzoyl-α-D-mannopyranosyl bromide (3) with 6-(N-acryloylamino)hexan-1-ol (1) as aglycone.These two glycosides were then coupled to the C-5 position of dUMP and UMP in the presence of Li2PdCl4 to give compounds (15)-(18) in 30-45percent yield.Their structure and those of the by-products (13), (14), (22), and (23) were determined by mass and NMR spectroscopies.The same reaction was successfully applied to the synthesis of triphosphate analogues (19)-(21) in 14-19percent yield.
