  • Role of Ring <i>Ortho</i> Substituents on the Configuration of Carotenoid Polyene Chains
    作者:Minsoo Kim、Hyunuk Jung、Albert C. Aragonès、Ismael Díez-Pérez、Kwang-Hyun Ahn、Wook-Jin Chung、Dahye Kim、Sangho Koo
    DOI:10.1021/acs.orglett.7b03930
    日期:2018.1.19
    The 9-(Z)-configuration was exclusively obtained in the carotenoid polyene chain irrespective of olefination and disconnection methods for terminal ortho-unsubstituted benzene rings. The 2,6-dimethyl substituents in the terminal rings secure an all-(E)-polyene structure. The single molecular conductance of the pure 9-(Z)-carotene was measured for the first time to be 1.53 × 10–4 ± 6.37 × 10–5G0, whose
    9-(Z)-构型仅在类胡萝卜素多烯链中获得,而与末端邻-未取代的苯环的烯烃化和断开方法无关。末端环中的2,6-二甲基取代基可确保全(E)-多烯结构。首次测得纯9-(Z)-胡萝卜素的单分子电导为1.53×10 –4 ±6.37×10 –5 G 0,其值为全(E)-的47%胡萝卜素((3.23×10 -4)±(1.23×10 -4)G 0)。

  • Fast Assembly and High-Throughput Screening of Structure and Antioxidant Relationship of Carotenoids
    作者:Dahye Kim、Gaosheng Shi、YunJi Kim、Sangho Koo
    DOI:10.1021/acs.orglett.8b03915
    日期:2019.2.1
    C-20 heptaenyl diphosphonate 4 was prepared for one-pot synthesis of carotenoids 1. Olefination with various aromatic aldehydes allowed fast assembly of the corresponding carotenoids. The SAR of carotenoids was investigated by high-throughput screening of ABTS and DPPH assays and their hierarchical clustering analysis. Antioxidant activity of carotenoids increased with the number of electron-donating substituents. Carotene la with multiple electron-donating substituents was most proficient, which showed better radical scavenging activities than beta-carotene and lycopene.
