  One-Pot Synthesis of 3-Methylflavones and Their Transformation into (E)-3-Styrylflavones via Wittig Reactions

  摘要：

  An efficient one-pot synthesis of 3-methylflavone derivatives is established. Furthermore, their transformation into phosphorus ylides, which are then used in the diastereoselective synthesis of (E)-styrylflavones through Wittig reactions, is also studied.

  Following our SAR studies on aromatase inhibitors, new compounds were designed by appropriately modifying the structure of flavone 1 using our previously reported CoMFA model. While the introduction of substituents on the 2-phenyl ring alone did not cause improvement in potency, these modifications and the removal of the 7-methoxy group led to compounds showing inhibitory activity in the nanomolar range, comparable to the marketed drug fadrozole.
