SYNTHESES TOTALES ET ETUDES DE LIGNANES BIOLOGIQUEMENT ACTIFS-I. APPLICATION DE LA REACTION D'ULLMANN A LA SYNTHESE DE BIARYLES PRECURSEURS DE LIGNANES BISBENZOCYCLOOCTADIENES

Several biaryls bearing various substituents on both rings were synthesized in a preparativ fashion, and in yields up to 88percent by a technical improvement on the classical Ullmann reaction.All these biaryls bear reactive functional groups (i.e. formyl, methoxycarbonyl, dimethoxycarbonylpropyl and butanolidylmethyl) in both the o and o' positions.The biaryls 9, 13, 21 and 26-33 are plausible synthons for bisbenzocyclooctadiene lignans such as schizandrin and steganacin.
