Reaction of 9a-hydroxyandrost-4-ene-3,17-dione (I) with benzenesulfinyl chloride and pyridine gives the corresponding sulfinate (II), which by treatment with TsOH in refluxing chloroform yields androsta-4,9(11)-diene-3,17-dione (III). Reaction of the androstadienedione (III) with acetylene by means of potassium tert-butoxide in THF affords the 17a-ethynyl derivative (IV), which is treated with phenylsulfenyl chloride and TEA at 70 C to provide the sulfenate ester (V). Rearrange-ment of sulfenate (V) by warming at 40 C gives the allene sulfoxide (VI), which is treated with sodium methoxide in methanol at 25 C to yield the enol ether sulfoxide (VII). Then, by refluxing in methanol, an equilibrium between sulfoxide (VII) and sulfenate (VIII) occurs. Reaction of the non-isolated sulfenate (VIII) with the thiophile trimethyl phosphite affords the 17a-hydroxy enol ether (IX), which is finally converted to anecortave acetate by either treatment with peracetic acid and NaHCO3 in dichloromethane or bromination with Br2 and pyridine in dichloromethane to give compound (X) followed by treatment with KOAc, KI and AcOH in refluxing acetone.

Androstenedione (II) was converted to the C-17 cyanohydrin (III) by treatment with either KCN and AcOH or with acetone cyanohydrin and NaOH. Ketalization of the remaining 3-keto group with ethylene glycol and trimethyl orthoformate led to (IV). The C-17 hydroxyl was then protected by formation of the acetaldehyde mixed ketal (V) by treatment with butyl vinyl ether. Addition of methyllithium to the cyano group, followed by acidic ketal hydrolysis furnished the pregnenedione (VI). Subsequent iodination of (VI) by means of iodine and calcium oxide gave iodo ketone (VII), which was further displaced by potassium acetate yielding the C-21 acetate ester (VIII). Finally, dehydration of the C-17 alcohol employing 70% aqueous sulfuric acid produced the title compound.
