T hree kinds of curcumin-type 1 ,5-diaryl-1 ,4-pentadien-3-one derivatives , 1 ,5-bis (3′-methyl-2′-thienyl )-1 ,4-pentadiene-3-ketone (Ⅰ ) , 1 ,5-diphenyl-1 ,4-pentadiene-3-ketone (Ⅱ) and 1 ,5-furyl-1 ,4-pentadiene-3-ketone (Ⅲ ) were designed and synthesized with aromatic aldehyde and ketone as the raw materials . T he composition and structure of as-synthesized products were characterized by elemental analysis ,infrared spectrometry and nuclear magnetic resonance (1 H NMR ,13C NMR) spectroscopy .Moreover ,the reaction conditions and reaction mechanisms were preliminarily discussed .Results show that target products can be obtained in relatively high yield at 30-50 ℃ in the presence of ethanol as the solvent and 8% NaOH solu-tion as the catalyst .
