The first synthetic route of novel 2′(β),3′(β)-C-dimethyl carbodine analogues is described. The key intermediate cyclopentenyl alcohol 11(β) prepared from Weinreb amide 4 via ring-closing metathesis (RCM) and vicinal dihydroxylation. Coupling of 12 with nucleosidic bases via the Pd(0) catalyzed reaction followed by stereoselective dihydoxylation and deprotection afforded the target carbocyclic nucleoside
