补充资料：奈非西坦
分子式 C14H18N2O2
分子量 246.06
CAS号 77191-36-7
化学名:Ｎ -(2,6- 二甲基苯基) -2 -(2-氧代－1－吡咯烷基)乙酰胺,白色晶体，熔点151～153℃，溶于水。
用途 是日本第一制药公司正在研制的吡咯烷酮类益智药,吡咯烷酮是主要的药效基团。奈非西坦可通过对大脑皮层的作用增强认知能力和防止学习、记忆的损伤,它不具有毒蕈碱受体激动剂和拮抗剂的特性,也不抑制乙酰胆碱酶的活性,因此它的抗遗忘和增强记忆的作用是通过提高大脑皮层乙酰胆碱释放而发生的。
制备 目前文献报道的合成方法主要有两种:一是吡咯烷酮乙酸在Ｎ,Ｎ’二环己基碳二亚胺(ＤＣＣ)存在下与2,6 二甲基苯胺缩合制得;二是以2－吡咯烷酮为起始原料,在强碱存在下与2－ 氯－ Ｎ (2,6 二甲基苯基)乙酰胺反应合成,后者可由氯乙酰氯和2,6 二甲基苯胺反应制得。
