PURPOSE: A process for preparing 4,17(20)-prostadien-3,16-dione from testosterone and intermediate compounds for preparing the same are provided to lower values for low density lipoprotein and cholesterol and to increase a value for high density lipoprotein. CONSTITUTION: The process for preparing 4,17(20)-E-prostadien-3,16-dione represented by formula VII from testosterone comprises the steps of: reacting testosterone represented by formula I with an alkane diol under a presence of an acid catalyst; reacting with a chrome oxide; reacting with an ethyl triphosphonium halide and a strong base; de-protecting; oxidizing with a selenium compound and a peroxide; and oxidizing it with a manganese oxide.
