Abstract

2-Alkoxy-4-hydroxy-5-oxocyclopent-1-eneheptanoic acid and its lower alkyl esters are reduced with metallic hydrides to yield the corresponding 3-hydroxy-5-oxo-cyclopent-1-eneheptanoic acid and its esters. The latter compounds are valuable intermediates in the preparation of pharmacologically active prostaglandin derivatives.
