The synthesis of phosphonate 1,2-disubstituted carbocyclic nucleosides with a cyclopentane ring is described following two different strategies: inclusion of the phosphonomethyl group before or after coupling of the carbocyclic moiety with the heterocyclic base. The diethyl [(trifluoromethanesulfonyl)oxy]methanephosphonate is the key phosphonylating agent for both the strategies.
