Total synthesis in the steroid series. II: d,l −3‐ethylenedioxy‐11 β‐hydroxy‐17‐oxymethyl‐D‐homoandrosta‐5: 16‐diene 18‐acid lactone (18 → 11), an intermediate to aldosterone

Attempts to transform potential intermediates prepared earlier into 18‐oxygenated steroids are described. One of the routes lead to the substiuted D‐homoandrostane derivative (XXIX) mentioned in the title.
