An efficient, versatile, and one-pot method for the preparation of novel fluorinated thiazolo- and oxazolo[3,2-a]pyrimidin-7-ones is described from 2-aminothiazoles or 2-amino-oxazoles and fluorinated alkynoates. This transformation, performed under transition-metal-free conditions, offers new fluorinated cyclized products with good to excellent yields. Moreover, the functionalization of these N-fused
描述了一种从 2-氨基噻唑或 2-氨基恶唑和氟化炔酸酯制备新型氟化噻唑并和恶唑并[3,2- a ]嘧啶-7-酮的有效、通用和一锅法。这种转化在不含过渡金属的条件下进行,提供了新的氟化环化产物,其收率良好至优异。此外,这些N-融合支架通过Suzuki-Miyaura和Sonogashira交叉偶联反应进行功能化,导致合成高度多样化的噻唑并和恶唑并[3,2- a ]嘧啶-7-酮。
