A short synthetic route to phosphonateprodrugs by olefincross-metathesis, which uses either (acyloxymethyl) or (hexadecyloxypropyl) allylphosphonate building blocks is described. A study of eight ruthenium catalysts including the Ru–indenylidene catalyst, which bears the N-heterocyclic carbene 1,3-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazol-2-ylidene, was undertaken. This method was applied to
