Lipase-mediated resolution of cis-4-cumyloxy-2-cyclopenten-1-ol and its utilization for enantioconvergent preparation of (-)-oxabicyclo[3.3.0]oct-6- en-3-one

Convenient preparation of both enantiomers of cis-4-cumyloxy-2- cyclopenten-1-ol from cyclopentadiene employing a lipase-mediated resolution was first established. An efficient enantioconvergent transformation of both enantiomeric products affording (-)-oxabicyclo[3.3.0]oct-6-en-3-one, an important building block of prostaglandin synthesis, was next established.
