SYNTHETIC STUDIES OF CONTRACETIVE DRUGS Ⅱ. THE SYNTHESIS OF 16α, 17α-DIHYDROXYPROGESTERONE ACETOPHENIDE
-
Abstract
The synthesis of 16α, 17α-dihydroxyprogesterone acetophenide (1) is reported. Starting from pregna-5,16-dien-3-ol-20-on, 3-acetate(Ⅳ), via potassium permanganate oxidation, condensation with acetophenone in presence of acid, followed by alkaline hydrolysis and Oppenauer oxdation, the object compound (1) was obtained. The △6-(Ⅵ) and △3,5-3-deoxy-(Ⅹ) derivative were also synthesized.
