develop a synthesis of 6-fluorinated cortexolones (synaflan, locacorten) based on androstenedione (AD), a product of microbial oxidation of sitosterol, we investigated the possibility of introducing fluorine at different stages of the synthesis: into the 3-ethylene ketal of 17~-hydroxyprogesterone (I) and esters of cortexolone (VIII, IX), the preparation of which from AD has been well studied [2, 4, 5]
