During studies related to the elaboration of prostaglandinprecursors we have reduced the ketonic carbonyl group of a number of optically active 2-substituted-4-hydroxy-2-cyclopentenone esters and ethers using sodiumborohydride and cerium trichloride under various conditions. High diastereoselectivity is achieved only with some 4-substituents.

Quinicacid is converted stereoselectively into a common cyclopentane intermediate useful for the synthesis of carbocyclic nucleosides prostaglandins and other important cyclopentane based compounds.
