The invention provides a new convergent approach for the synthesis of 2′-fluoro-6′-methylene-carbocyclic adenosine (FMCA) from a readily available starting material (Vince lactam) in fourteen steps. An efficient and practical methodology for stereospecific preparation of a versatile carbocyclic key intermediate, D-2′-fluoro-6′-methylene cyclopentanol by diazotization, elimination, stereoselective epoxidation, fluorination and oxidative reduction of the Vince lactam in twelve steps is also provided.
