An efficient synthesis of (1S,4R)-(-)-4-tert-butyldimethylsilyloxy-2-cyclopentenyl acetate and (1R,4S)-(-)-4-tert-butyldimethylsilyloxy-2-cyclopentenol is described utilizing a furfuryl alcohol rearrangement, followed by a lithium aluminum hydride reduction with high facial selectivity and an efficient enzymatic resolution with pancreatin. Both of these intermediates were successfully utilized in the preparation of the carbocyclic nucleoside 9N-[(1'R,3'R)-trans-3'-hydroxycyclopentanyl]adenine hydrochloride, an agent which inhibits the formation of tumor necrosis factor-alpha.
