以N-甲基-4-哌啶酮和芳甲醛衍生物为原料,分别以10%的氢氧化钠乙醇溶液和干燥的氯化氢气体作催化剂,室温下羟醛缩合反应7~8h,TLC检测反应进程,合成了3种N-甲基-3,5-二芳亚甲基-4-哌啶酮衍生物,质量收率达到49%以上,并以。HNMR结合熔点对其结构进行了表征。结果表明,该合成路线反应条件温和,操作简便。
Starting from N-methyl-4-piperidone and formaldehyde derivatives, the targeted compounds were synthesized with 10% alcoholic NaOH or dry hydrogen chloride as catalyst via aldol condensation reaction at room temperature for 7- 8 h. The reaction was monitored by TLC. Three 3,5-bis(arylidene)-4-piperidones were successfully synthesized with the yields above 49%. The structures were characterized by 1 H NMR and melting points measurement. This was a convenient and efficient method with high yields. The compounds synthesized are used for antitumour evaluation.
