AbstractIn connection with earlier work on the synthesis of 9β, 10α‐steroids, a new and practical synthesis of rac‐17α‐hydroxy‐des‐A‐androst‐9‐en‐5‐one (19) has been developed, based on a novel stereoselective condensation of 7‐hydroxy‐1‐nonen‐3‐one (3) with 2‐methyl‐cyclopentane‐1, 3‐dione (9) and subsequent transformations of the resulting tricyclic diene ether 12.
