Abstract
A process for the synthesis and purification of F-series prostaglandin compounds and synthetic intermediates used to prepare them. The synthetic intermediates are solid and may be purified by precipitation and therefore may form the representative F-series prostaglandin compounds such as latanoprost, bimatoprost, fluprostenol, cloprostenol, and substituted analogs therefrom in highly pure forms.
