The synthesis of (E)-3′-phosphonoalkenyl and 3′-phosphonoalkyl modified nucleoside analogues with a β-d-erythrofuranose moiety is reported. The highly stereoselective olefin cross-metathesis reaction was applied to introduce the phosphonoalkenyl group at the 3′-position of the sugar moiety with absolute (E)-selectivity. The 3′,6′-cyclomonophosphonic acids of 3′-phosphonoethyl-β-d-erythrofuranosyl nucleosides
