Abstract
Dinoprostone para-substituted phenyl esters were synthesized in attempt to improve the solid-state stability of the parent prostaglandin. A phenol series covering a wide melting-point range was employed, and a linear relationship was observed between the phenol melting points and the resulting prostaglandin C1-ester melting points. The crystalline esters showed improved solid-state stability over the parent compound, and many esters were biologically active.
