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。

A general approach to 3-fluoro-, 3-chloro-, and 3-bromoquinolines which relies on organosilane-promoted Friedländer reaction of α-haloketones is described. The scope of the methylene component as well as influence of the organosilane component on the outcome of the reaction is studied. The method can be used under parallel synthesis conditions.
