In order to improve the modest oral activity of PGE 2 as an inhibitor of gastric acid secretion, analogs were prepared and tested orally in histamine-challenged rats. Insertion of a double bond at C-4, resulting in the 4,5-allene analog of PGE 1 , ga

A convenient synthesis of 5,17-dihydroxy-5α,17α-19-norpregn-20-yn-3-one in multigram quantities from norethindrone is reported. Confirmation of the structural assignment of this major photodegradation product of norethindrone is thus made.
