    The Constituents of Schizandra chinensis BAILL. V. The Structures of Four New Lignans, Gomisin N, Gomisin O, Epigomisin O and Gomisin E, and Transformation of Gomisin N to Deangeloylgomisin B[Reference: WebLink]
    Four new dibenzocyclooctadiene lignans, gomisin N (1), Gomisin O (2) and gomisin E (4), and epiGomisin O (3), together with a known lignan (+)-deoxyschizandrin (5) were isolated from the fruits of Schizandra chinensis BAILL. (Schizandraceae).
    The structures of the new lignans were elucidated by chemical and spectral studies. The transformation of 1 to deangeloylgomisin B (debenzoylgomisin C) (6) is also described.

    Asymmetric total synthesis of dibenzocyclooctadiene lignan natural products.[Pubmed: 16238330 ]
    Full details of the asymmetric total syntheses of the dibenzocyclooctadiene lignans interiotherin A, angeloylgomisin R, Gomisin O, and gomisin E (epiGomisin O) are presented.
    The syntheses were based on a unified synthetic strategy involving a novel crotylation using the Leighton auxiliary that occurred with excellent asymmetric induction (>98:2 enantiomeric ratio), a diastereoselective hydroboration/Suzuki-Miyaura coupling reaction sequence, and an atropdiastereoselective biarylcuprate coupling, both of which occurred with total (>20:1) stereocontrol. The syntheses were achieved in six to eight steps from simple aromatic precursors.
