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.

Photochemical Cycloadditions. III. Addition of 4-Substituted 2-Cyclopentenones to Allene; Configuration Determination by Lanthanide-Induced Shift Studies

Photoaddition of 4-substituted 2-cyclopentenones to 1,2-propadiene gave mixtures of the head-to-head and head-to-tail cycloadducts in a ratio of ca. 90:10.The stereoisomeric composition was sensitive to solvent changes, as was the chemical yield of the cycloadducts.Under otherwise identical conditions the highest yields were obtained in non-polar solvents.The configurations of the cycloadducts were determined by LIS and 13C NMR studies.
