  • Multistep Phase-Switch Synthesis by Using Liquid-Liquid Partitioning of Boronic Acids: Productive Tags with an Expanded Repertoire of Compatible Reactions
    作者:Sam Mothana、Jean-Marie Grassot、Dennis G. Hall
    DOI:10.1002/anie.200906710
    日期:2010.4.6
    Tagging along: A system for phase‐switch synthesis has been developed. The boronic acid functionality is used as a phase tag that complexes to sorbitol and facilitates compound transfer from an organic solvent to water at high pH. The phase tag can then be used in a productive reaction step to generate targeted products, thereby eliminating purification by silica gel chromatography.

  • Dramatic Effect of the Gelling Cation on the Catalytic Performances of Alginate-Supported Palladium Nanoparticles for the Suzuki–Miyaura Reaction
    作者:Mélanie Chtchigrovsky、Yi Lin、Kahina Ouchaou、Manon Chaumontet、Mike Robitzer、Françoise Quignard、Frédéric Taran

    This work describes the preparation and characterization of a library of alginate-supported palladium nanoparticles together with their catalytic capabilities to promote the Suzuki-Miyaura reaction. Using the chelating properties of the carboxylate functions of the alginate matrix a series of Ca, Ba, Mn, Zn, Ni, Ce, Cu, and Co alginate gels were first prepared and then reacted with Pd2+ salts. Partial exchange of metal cations followed by Pd reduction into palladium nanoparticles and supercritical CO2 drying generated a panel of bimetallic alginate aerogels. Physical characterizations of these materials showed a significant influence of both the gelling metal nature and the Pd loading on surface areas and nanoparticles size. A comparative study of the catalytic performances of these heterogeneous catalytic systems is then reported for the Suzuki-Miyaura reaction. This study highlighted the superior performances of palladium nanoparticles supported on copper-alginate aerogels. This heterogeneous catalyst showed high catalytic activities as illustrated by a TOF value of 10 s(-1) and a TON value close to 10(6). The robustness of the catalyst allowed several reuses with no significant loss of activity or metal leaching.

  • An Easy Access to 2-Substituted Azulenes from Azulene-2-boronic Acid Pinacol Ester

    Azulene-2-boronic acid pinacol ester was conveniently transformed into 2-substituted azulenes bearing carboxyl, formyl, ester, or amino groups, which are difficult to access by conventional methods. Furthermore, the azulene-2-carboxylic acid thus synthesized was subjected to the Ugi four-component condensation to obtain a dipeptide-type product containing an azulene skeleton.
