Studies towards a total synthesis of the antiprogestine onapristone

Valentin S. Enev; Orlin Petrov; Harribert Neh; Klaus Nickisch

Abstract Starting from the readily available Eder-Hajosh ketone 2 a stereoselective method for synthesis of arylated hydrindenone 14 was developed. One pot Li/NH 3 reduction and trapping of the generated enolate with activated Michael acceptor gave a properly substituted BCD-ring precursor 22 . Attempted B ring closure with the model compound 22 failed under various conditions.
