Racemic endo-4-acetoxybicyclo[3.2.1]oct-2-ene furnishes enantiopure (+)-bicyclo[3.2.1]oct-3-en-2-one and its dihydro derivative leaving enantiopure (+)-endo-4-acetoxybicyclo[3.2.1]oct-2-ene in a phosphate buffer solution in the presence of a lipase (Candida antarctica) and palladium(II) chloride. Utilizing the products, a diastereocontrolled route to some cyclopentanoid monoterpenes has been established
