The synthesis of α-fluorinated arylpropionic acids 5 as analogues of the nonsteroidal anti-inflammatory agents (NSAIDs) flurbiprofen 1, ibuprofen 3 and naproxen 4 is accomplished by the oxidation of the corresponding primary alcohols 9 The latter are accessible on two different pathways showing their general applicability by variation of the aromatic moiety. Furthermore the influence of the fluorine
的α-氟化芳基丙酸的合成5作为非甾体抗炎剂的类似物(NSAIDs)的氟比洛芬1,布洛芬3和萘普生4由相应的伯醇氧化来完成9后者是在两个不同的途径示出访问他们的通过改变芳族部分的一般适用性。此外,通过化合物5c的比较X射线研究显示了氟取代基对晶格中酸部分的构象的影响。
