摘 要:在碳酸钠和氢氧化钠催化下,β-紫罗兰酮和5,6-环氧-β-紫罗兰酮与芳香醛于室温下研磨1~15 min,制备了8种新型含紫罗兰酮基查尔酮,其结构经1H NMR、MS、IR和元素分析表征。结果表明,β-紫罗兰酮、苯甲醛、Na2CO3与NaOH的物质的量比为20∶20∶5∶15时,收率可达87.1%~94.8%,苯甲醛环上吸电子基团可促进反应进行。Condensation of β-ionone and 5,6-epoxyl-β-ionone with aromatic aldehydes by sodium carbonate and sodium hydroxide was carried out to afford eight novel ionone-containing chalcones at room temperature for 1 - 15 min by grinding, and their structures were characterized by ^1H NMR, MS, IR and elemental analysis. The effeets of substituents, the types and amounts of catalysts on the reaction were studied. The results show that the yield is 87. 1% - 94. 8% when the molar ratio ofβ-ionone, benzalaldehyde, sodium carbonate and sodium hydroxide is 20: 20: 5: 15, and electron withdrawing group promotes the condensation.
