The problem of the synthesis of corticosteroids from the commonly used steroid raw material with an unsubstituted ring C (diosgenin and soiasodin) has already been solved by microbiological(More)
In the present work, we synthesized in a similar way 3e-hydroxy-5=-androst-9(ll)-en-17one (VI) from 38-acetoxy-5=-andros~an-17-one (I), which is also a transformation product of tigogenin [3], and studied the subsequent conversion of VI into llS,17B-dihydroxy-17~-methyl9=-fluoro-5=-androstan-3-one (XIII) and(More)
