which included Stille, Suzuki, enol ether, Knoevenagel, and the Mukaiyama coupling reactions, revealed the Knoevenagel approach superior for preparing large quantities of drug substance for evaluation. The overall process utilized some classical chemistry. Fischer indole cyclization, followed by a Vilsmeier−Haack formylation and a Knoevenagel condensation gave immediate access into the proper carbon framework
MDL 103371 是一种 N-甲基-d-天冬氨酸 (NMDA) 型甘氨酸受体拮抗剂,可用于治疗中风。对五种不同的合成路线(包括 Stille、Suzuki、烯醇醚、Knoevenagel 和 Mukaiyama 偶联反应)的评估表明,Knoevenagel 方法在制备大量用于评估的原料药方面具有优势。整个过程使用了一些经典化学。Fischer 吲哚环化,然后是 Vilsmeier-Haack 甲酰化和 Knoevenagel 缩合,可以立即进入目标分子的适当碳框架。用于硝基还原的独特氢化催化剂和溶剂系统,然后是腈的两步酸碱水解,得到粗产物。
