    From Central to Axial to Central Chirality: Enantioselective Construction of the trans -4,5,9,10-Tetrahydroxy-9,10-dihydrophenanthrene System

    EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 34 2007
    Georgi Stavrakov
    Abstract Enantioselective synthesis of the core trans -4,5,9,10-tetrahydroxy-9,10-dihydrophenanthrene parent system of the antibiotics benanimicin, pradimicin and FD 594 has been accomplished. The synthesis employs a chiral tether approach and makes use of efficient central to axial to central chirality transfer. Key to success was an "imine-directed" atropdiastereoselective Ullmann coupling under mild reaction conditions. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007) [source]

    Synthesis and Characterization of Carbazole-Based Dendrimers with Porphyrin Cores

    EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 17 2006
    Ting Hua Xu
    Abstract A series of novel dendritic carbazole-based porphyrins [T(Cz-Gn)Ps] have been synthesized by a combination of Ullmann coupling and Adler condensation reactions and their intramolecular energy-transfer properties have been studied by absorption and steady-state fluorescence spectroscopy. It has been found that the light-harvesting capabilities of T(Cz-Gn)Ps increase with increasing generation, but that the efficiency of the energy transfer decreases from T(Cz-G0)P to T(Cz-G2)P due to the Förster energy-transfer process. In addition, these dendritic macromolecules can emit intense red light with high fluorescence quantum yields and so may find applications in photonic devices. (© Wiley-VCH Verlag GmbH & Co.
