An optimized total synthesis of the 2-amino-6-chloro-4-cyclopropyl-7-fluoro-5-methoxy-pyrido[1,2-c]pyrimidine-1,3-dione core structure of a new fluoroquinolone-like class of antibacterial agents is described. This synthesis is highlighted by a nearly quantitative ring-closing reaction to form the pyrido[1,2-c]pyrimidine core. This bicyclic ringsystem serves as a scaffold for a family of biologically
一种新型氟喹诺酮类的2-氨基-6-氯-4-环丙基-7-氟-5-甲氧基-吡啶并[1,2 - c ]嘧啶-1,3-二酮核心结构的优化全合成描述了抗菌剂。该合成通过形成吡啶并[1,2- c ]嘧啶核的近乎定量的闭环反应而突出。这种双环系统用作生物活性化合物家族的支架。
