以柚皮苷为原料,经酸催化水解、O-甲基化或O-异戊烯基化反应、碱催化的开环反应合成了天然查尔酮卡瓦胡椒素A (1)和查尔酮异戊烯基醚衍生物2;然后以查尔酮12为底物,分别通过Mannich反应对其3’位进行了胺甲基化修饰,合成了14个未见文献报道的新型查尔酮Mannich碱衍生物316. 所合成化合物的结构已由核磁共振谱、红外光谱和质谱所证实,并对所合成的查尔酮及其Mannich碱衍生物进行了乙酰胆碱酯酶(AChE)抑制活性测试,结果发现查尔酮Mannich碱衍生物359具有良好的AChE抑制活性.

Chalcone flavokawain A (1) and chalcone prenyl ether derivative 2 were synthesized from naringin, through glycoside hydrolysis, O-methylation or O-prenylation, and base-catalyzed ring-opening reaction. Based on Mannich reaction of chalcone 1 and chalcone prenyl ether derivative 2, fourteen new chalcone Mannich base derivatives 316 were synthesized. The aminomethylation occurred preferentially at 3'-C position of chalcones. The structures of all synthesized compounds were determined by MS, NMR and IR spectra. All the synthetic compounds were evaluated for acetylcholinesterase (AChE) inhibitory activity. The results show that chalcone mannich base derivatives 35, 9 exhibit good AChE inhibitory activity.

Key words: chalcone, flavokawain A, Mannich base, synthesis, acetylcholinesterases inhibitory activity
