Abstract
A reproducible and scalable method has been developed for the synthesis of a series of 3,6-substituted pyrazolo[1,5-a]pyrimidines, which are the basis for the rational design of selective inhibitors of AMP-activated protein kinase. Regarding the formation of new types of the carbon skeleton, the applicability of the Suzuki–Miyaura cross-coupling using the Buchwald ligands to form C–C bond in the sterically hindered position 6 of 5,7-dimethyl-substituted pyrazolo[1,5-a]pyrimidine has been shown.
摘要
为合成一系列 3,6 取代的吡唑并[1,5-a]嘧啶开发了一种可重复和可扩展的方法,该方法是合理设计 AMP 活化蛋白激酶选择性抑制剂的基础。关于新型碳骨架的形成,利用布赫瓦尔德配体在 5,7 二甲基取代的吡唑并[1,5-a]嘧啶的立体受阻位置 6 上形成 C-C 键的 Suzukii-Miyaura 交叉偶联的适用性已经得到证明。
