  • Asymmetric Synthesis of Antimicrotubule Biaryl Hybrids of Allocolchicine and Steganacin
    作者:Agnès Joncour、Anne Décor、Jian-Miao Liu、Marie-Elise Tran Huu Dau、Olivier Baudoin

    its stereochemical information to the biaryl axis. The coupling conditions were optimized, and two biphenylphosphane ligands (DavePhos and S-Phos) were found to give the highest yields and diastereoselectivities. A three-element stereochemical model was proposed to explain the observed diastereoselectivities. In a second key step, the medium ring of the target molecules was formed by a stereoselective

  • Synthetic Approaches to Amino Analogues of <i>N</i>-Acetylcolchinol
    作者:Virginie Colombel、Olivier Baudoin
    DOI:10.1021/jo900632a
    日期:2009.6.5
    A straightforward synthesis of aminodibenzoxepines, new analogues of N-acetyleolchinol, is reported by using two different strategies. The first strategy involves a Grignard addition, a biaryl Suzuki-Miyaura coupling, and a HF-mediated cyclodehydration as key steps. A second strategy, better adapted to the synthesis of analogues bearing a benzylic substituent, was designed by inverting the order of the Grignard addition and the biaryl coupling. This allowed the rapid and reliable production of a series of substituted aminodibenzoxepines. A chelate model was proposed to account for the diastereoselectivity observed in the Grignard addition step.
  • Synthesis of antimicrotubule dibenzoxepines
    作者:Virginie Colombel、Agnès Joncour、Sylviane Thoret、Joëlle Dubois、Jérôme Bignon、Joanna Wdzieczak-Bakala、Olivier Baudoin
    DOI:10.1016/j.tetlet.2010.04.039
    日期:2010.6
    New dibenzoxepines 5a-i bearing various substituents on B- and C-rings were synthesized in a straightforward manner using a Suzuki-Miyaura coupling, a Grignard addition, and a cyclodehydration as key steps. The antimicrotubule activity of all analogues was evaluated and compared to reference compounds. Compounds 5d-f displayed the highest activity for this type of allocolchicinoids to date.

  • A Novel 1,3-Central-to-Axial Chirality Induction Approach to Cyclooctadiene Lignans
    作者:Olivier Baudoin、Anne Décor、Michèle Cesario、Françoise Guéritte
    DOI:10.1055/s-2003-42039
    日期:——
    The catalytic asymmetric synthesis of an axially chiral biaryl, potentially useful intermediate in the synthesis of dibenzocyclooctadiene lignans, has been performed. The key step consisted of a diastereoselective Suzuki coupling between a chiral benzylic alcohol and a sterically hindered boronic ester. The 1,3-induction from the benzylic stereocenter to the biaryl axis proceeded with very good diastereoselectivity.
