    摘要: Described is a process of preparing 3-aryl, 4-aryloxy furan-5-ones which are useful as inhibitors of cyclooxygenase-2 (COX-2). Such compounds are useful as anti-inflammatory agents. The process is directed to an asymmetric synthesis which involves: a trisubstituted styrene derivative preparation via Horner-Wadsworth-Emmons reaction and subsequent one pot trifluoromethylation of the allylic alcohol; preparation of the .alpha.-hydroxyl ketone using Sharpless asymmetric dihydroxylation and Swern oxidation; the esterification of the .alpha.-hydroxyl ketone with the phenoxy acetic acid; and the Dieckman condensation of the resulting ester.
