摘要

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 substituent towards the conformation of the acid ...
