2-Fluoromalonic acid is a useful building block for the synthesis of selectively fluorinated heterocycles. In the presence of phosphorylchloride, chlorinated fluoro-quinoline and fluoro-pyridopyrimidinone derivatives can be prepared in a single step by an efficient tandem chlorination-cyclisation process. Functionalisation by Suzuki cross-coupling or SNAr processes allowed for the rapid construction
2-氟丙二酸是合成选择性氟化杂环的有用构件。在磷酰氯的存在下,氯化氟-喹啉和氟-吡啶并嘧啶酮衍生物可以通过有效的串联氯化-环化工艺一步制备。通过 Suzuki 交叉偶联或 S N Ar 工艺的功能化允许以高产率快速构建一个包含 30 种新型多取代选择性氟化喹啉和吡啶并嘧啶酮衍生物的小型文库,并带有多种取代基。
