  New Strong Base Synthesis of Symmetrical 1,5-Diaryl-1,3,5-pentanetriones from Acetone and Benzoate Esters

  摘要：

  Lithium hexamethyldisilazide (LiHMDS) was used to condense substituted benzoate esters with acetone to afford symmetrical 1,5-diaryl-1,3,5-pentanetriones that were isolated, characterized (including a representative X-ray crystallographic analysis), and acid cyclized to the respective 2,6-diaryl-4H-pyran-4-ones.
