Estradiene dione-3-keta (CAS 5571-36-8) is a 3-ethylene ketal-protected steroid intermediate. The ketal protection masks the 3-ketone, allowing selective functionalisation at other positions before deprotection. It is used in the synthesis of antiprogestins such as mifepristone and other hormonal therapeutics.
