摘要：

Starting from the readily available Eder-Hajosh ketone 2 a stereoselective method for synthesis of arylated hydrindenone 14 was developed. One pot Li/NH3 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. (C) 1997 Elsevier Science Ltd.
