  Design, synthesis and antitumor activity of a series of novel coumarin–stilbenes hybrids, the 3-arylcoumarins

  摘要：

  A series of novel coumarin-stilbenes hybrids called 3-arylcoumarins were synthesized via Perkin reaction and evaluated as potential antitumor agents. The results showed that some compounds exhibited in vitro activity against KB, KV, MCF-7, MCF-7/ADR cell lines to some extent. Compound 3a showed remarkable effect against KB tumor cells with an IC50 value of 5.18 mu mol/L. (C) 2010 Yong Zou. Published by Elsevier B.V. on behalf of Chinese Chemical Society.

• Hydroxyl Substitutional Effect on Selective Synthesis of <i>cis, trans</i> Stilbenes and 3-Arylcoumarins Through Perkin Condensation

  The substitutional effect in the selective synthesis of cis, trans stilbenes and 3-arylcoumarins has been described. The regio- and geometrical selectivity for synthesis of stilbene derivatives under the Perkin strategy strongly depends on the presence or absence of hydroxyl group as well as their positions in the phenyl ring. As a result, practical synthetic strategies were established for preparing various natural stilbenes including combretastatin A-4, pterostilbene, and resveratrol with satisfactory yields (49.2-63.7%).
