Synthesis of a novel class of 7-amino-3-pyrimidinyl-pyrazolo[1,5-a]pyridine antiherpetic compounds is described. The synthetic methodology is designed to allow for rapid analog synthesis around the C-3 and C-7 positions of the pyrazolo[1,5-a]pyridine. The 7-chloropyrazolo[1,5-a]pyridine D, produced through an azirine rearrangement, served as a key building block. Two complementary methodologies for
描述了新型的7-氨基-3-嘧啶基-吡唑并[1,5- a ]吡啶抗疱疹化合物的合成。设计合成方法以允许在吡唑并[1,5- a ]吡啶的C-3和C-7位置附近进行快速类似物合成。通过叠氮基重排产生的7-氯吡唑并[1,5- a ]吡啶D是关键的组成部分。描述了用于构建C-3嘧啶的两种互补方法。这些方法包括开发利用炔基酮或烯酮的新型环化反应,以得到高度取代的嘧啶。概述的策略促进了C-3或C-7位置的后期操作,为快速模拟合成提供了灵活性。
