The preparation and enzymatic resolution of several cis-mono-4-O-protected-2-cyclopenten-1,4-diols are described. The process starts with inexpensive furfuryl alcohol and lends itself to the preparation of multigram quantities of various protected, optically active 2-cyclopenten-1,4-diol derivatives. Stereoselective reduction of 4-O-protected-2-cyclopentenone to the cis-mono-O-protected-2-cyclopenten-1,4-diol using LiAlH4/LiI or Red-Al/NaI is described. Subsequent pancreatin-promoted, stereoselective acylation was conducted on these cis-(+/-)-mono-O-protected-cyclopenten-1,4-diols to afford the corresponding alcohols and acetates in moderate to excellent enantioselectivities.

An efficient synthesis of a prostaglandin synthon (+/-)-cis-oxabicyclooct-6-en-3-one (1) has been developed using cyclopentadiene (2) as starting material.Employing the same methodology optically active (1) is also synthesized in low optical purity.
