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.
