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
An efficient enantiodivergent route to α-cuparenone, a sesquiterpene isolated in both enantiomeric forms, has been developed utilizing a chiral cyclopentanoid starting material having a latent meso structure.
