[Synthesis of Butyl 6alpha-Fluoro-11beta-hydroxy-16alpha-methyl-3,20-dioxo-1,4-pregnadien-21-oate (Fluocortin Butylester) (author's transl)].
Among the metabolites of fluocortolone (1) there was found the alpha-keto acid 4a. This acid, as well as the esters 4b--4k were synthesized and the butyl ester 4c was chosen for local anti-inflammatory therapy.
