  名称：

  [60]Fullerene–flavonoid dyads

  摘要：

  A range of fullerene-chalcone, fullerene-flavone, and fullerene-chromone dyads, including a bis(flavonyl)-fullerene dyad, were prepared by 1,3-dipolar cycloaddition reactions of azomethine ylides to C-60 and by cyclopropanation of C-60 with flavonyl malonates. Synthetic and natural flavonoid derivatives were used as starting materials. (C) 2004 Elsevier Ltd. All rights reserved.
