  Synthesis and antifungal activities of natural and synthetic biflavonoids

  摘要：

  The synthesis of some natural and synthetic biflavonoids was performed in good overall yields starting from readily available materials via high yielding aldol and Ullmann condensations. Some of these compounds, especially bichalcones, display an interesting activity against fungi, higher than that of the corresponding monomers. (C) 2011 Elsevier Ltd. All rights reserved.
