    摘要: Novel 16-phenoxy and 16-(o, m or p)-substituted phenoxy derivatives of (dl)-9-keto-11.alpha.,15.alpha.-dihydroxy-17,18,19,20-tetranorprosta-4,5,13-trans-trienoic acid, the pharmaceutically acceptable, non-toxic lower alkyl esters and salts thereof and processes for the production of such compounds. These compounds possess prostaglandin-like activities and thus are useful in the treatment of mammals where prostaglandins are indicated. They are particularly useful as inhibitors of gastric acid secretion; and as agents for the control of asthmatic attack, because of their bronchodilating activity.

    摘要: The tricyclic intermediate ##STR1## is prepared in a three step sequence from the bicyclic intermediate ##STR2## The key step of this process involves the addition of a Grignard reagent to a mixed anhydride. Tricyclic compound of formula (I) may be readily converted by known methods to valuable steroids.
