摘要：

1,1,1-Trifluoro-4-arylbutan-2,4-diones undergo a smooth reaction with dialkyl acetylenedicarboxylates and triphenylphosphine to produce phosphorus ylide intermediates, which undergo stereoselective intramolecular Wittig reaction to produce dialkyl 4-arcarbonyl-3-trifluoromethyl-cyclobut-2-ene-1,2-dicarboxylates in good yields.
