在无溶剂条件下, α,β-不饱和醛与芳香酮在室温下研磨得到2,4-共轭二烯酮, 随后, 2,4-共轭二烯酮与过量芳香酮在NaOH存在下进一步发生Michael加成反应, 快速而高效地合成了3-芳乙烯基-1,5-二酮类化合物. 该法与传统的溶液法相比具有不使用溶剂和催化剂, 反应条件温和, 反应时间短, 操作简便等优点.

A convenient procedure for the synthesis of 3-styryl-1,5-dicarbonyl compounds has been developed under solvent-free grinding conditions. α,β-Unsaturated aldehydes react with aromatic ketones to give the corresponding dienone products, then followed by a Michael addition producing 3-styryl-1,5-dicarbonyl compounds in the presence of NaOH at room temperature. The advantages of this procedure are solvent-free, catalyst-free, mild reaction conditions, simple procedure, and short reaction time.

Key words: solvent-free, grinding, aldol-Michael addition, 1,5-diketones
