The present invention provides a novel method for preparing lacosamide with high chiral purity from D-serine. The method of the present invention can obtain lacosamide with high chiral purity in a high yield through a simple and environmentally-friendly process and thus can be easily applied to mass production.

National Institute of Neurological Disorders and Stroke Anticonvulsant Screening Program for seizure protection in the maximal electroshock (MES) and subcutaneous Metrazol models. Comparing activities for two series of substituted aryl regioisomers (2′, 3′, 4′) showed that 4′-modified derivatives had the highest activity. Significantly, structural latitude existed at the 4′-site. The SAR indicated that
已经探索了临床抗癫痫药 ( R )-拉科酰胺 [( R ) -N-苄基 2-乙酰氨基-3-甲氧基丙酰胺,( R ) -3 ] 中N-苄基的构效关系 (SAR) 。制备了 43 种化合物,然后在国家神经疾病研究所和中风抗惊厥筛查计划中评估其在最大电击 (MES) 和皮下美曲唑模型中的癫痫保护作用。比较两个系列取代的芳基区域异构体(2'、3'、4')的活性表明,4'-修饰的衍生物具有最高的活性。值得注意的是,结构纬度存在于 4' 位点。SAR 表明非庞大的 4'-取代(R )- 3衍生物表现出极好的活性,与它们的电子特性无关。几种化合物在 MES 测试中的活性与 ( R ) -3的活性相当或超过,并且超过了对传统抗癫痫药苯妥英、苯巴比妥和丙戊酸盐观察到的活性。

from the C(2) site. This paper validates this hypothesis. Twelvederivatives of N-benzyl-2-acetamidopropionamide have been prepared in which six different heteroatom substituents (chloro, bromo, iodo, oxygen, nitrogen, and sulfur) were incorporated at the C(3) site. Highly potent activities were observed for the two oxygen-substituted derivatives, N-benzyl-2-acetamido-3-methoxypropionamide (18) and N
