    名称:
    Enantioselective synthesis of (+)-O-trimethylsappanone B and (+)-O-trimethylbrazilin
    摘要:
    The homoisoflavanoid (+)-O-trimethylbrazilin (1b) was prepared in 70% yield and 92% ee by acid-catalyzed rearrangement of O-trimethylsappanol (8) prepared by reduction of (R)-(-)-O-trimethylsappanone B (2b). The key step in the synthesis of (R)-(-)-2b is the reagent-controlled highly enantioselective hydroxylation (94%) of the sodium enolate of (+/-)-4-chromanone (3b) with the (+)-8,8-dichlorocamphorsulfonyl oxaziridine 7b.

  • Synthesis of 3-(2-Olefinbenzyl)-4<i>H</i>-chromen-4-one through Cyclobenzylation and Catalytic C–H Bond Functionalization Using Palladium(II)

    and benzyl bromide to produce homoisoflavonoid. The second step involves intermolecular Pd-catalyzed π-chelating-assisted C–H bond olefination. Using the C-2/C-3 double bond of chromone, palladium-catalyzed aryl C–H bond activation can be functionalized to generate ortho-olefination derivatives in moderate to high yields.
    开发了一种有效的策略,可以分两步合成3-(2-烯烃苄基)-4 H -chromen -4-one。第一步是(E)-3-(二甲基氨基)-1-(2-羟基苯基)丙-2-烯-1-酮与苄基溴之间的环苄基化反应,以生成均异黄酮。第二步涉及分子间Pd催化的π螯合辅助的C–H键烯化。使用色酮的C-2 / C-3双键,可以将钯催化的芳基C–H键活化功能化,以中等至高收率生成邻烯化衍生物。
