  • Bibenzyl derivatives from the liverwort Ricciocarpos natans
    作者:Siegmund Kunz、Hans Becker
    DOI:10.1016/s0031-9422(00)89795-2
    日期:1994.6
    A new bibenzyl (2,5,4'-trihydroxybibenzyl), a dimeric bisbibenzyl (6',6'''-bis-riccardin C) and a phenylethyl-cyclohexenone (prelunularin) were isolated from the liverwort Ricciocarpos natans grown in axenic culture. All structures were established on the basis of spectral data and chemical evidence.
  • Isolation, Structure Elucidation, and Chemical Derivatization of a New Cyclic Bisbibenzyl Dimer, Pusilatin E, from the Liverwort <i>Riccardia multifida</i> subsp. <i>decrescens</i>
    作者:Tatsuhiko Yoshida、Masao Toyota、Yoshinori Asakawa
    DOI:10.1021/np9605697
    日期:1997.2.1
    A new cyclic bisbibenzyl dimer (1) has been isolated from the MeOH extract of the liverwort Riccardia multifida subsp. decrescens, together with two previously known bisbibenzyls [riccardin A (2) and marchantin I (3)] and a norneolignan [egonol 2-methylbutanoate (4)]. Extensive H-1- and C-13-NMR spectral measurements and chemical derivatization allowed the structure of dimeric riccardin A to be defined; it has been named pusilatin E (1).
  • Phenolic constituents of the liverwort: Four novel cyclic bisbibenzyl dimers from Blasia pusilla L
    作者:Tatsuhiko Yoshida、Toshihiro Hashimoto、Shigeru Takaoka、Yukiko Kan、Motoo Tori、Yoshinori Asakawa、John M. Pezzuto、Thitima Pengsuparp、Geoffrey A. Cordell
    DOI:10.1016/0040-4020(96)00889-7
    日期:1996.11
    Four novel, cyclic, bisbibenzyl dimers (pusilatins A-D), six bibenzyl derivatives, apigenin , shikimic acid and five orsellinic acid derivatives have been isolated from the methanolic extract of the liverwort Blasia pusilla L. and their structures characterized by a combination of spectral data, chemical modification and X-ray crystallographic analysis. The previously assigned structure of pusilatin

  • Total Syntheses of Pusilatins A–C, Liverwort-Derived Macrocyclic Bisbibenzyl Dimers
    作者:Takahiro Yamada、Hiromu Takiguchi、Ken Ohmori、Keisuke Suzuki
    DOI:10.1021/acs.orglett.8b01366
    日期:2018.6.15
    The total syntheses of pusilatins A (2), B (3), and C (5), macrocyclic bisbibenzyl dimers isolated from Japanese liverwort are reported. The common monomeric unit (6) was prepared via macrocyclization of an o-sulfinylfluorobenzene derivative by SNAr attack of an internal phenol, which was exploited for site-selective dimerizations en route to 2, 3, and 5.
