4-Benzoyl-5-phenyl-2,3-furandione 1 reacts with acetanilides 3a-d under different conditions and gives the open-chain dibenzoylacetic acid derivatives 5a-c, 6a,b and an oxazole derivative 8. It has been demonstrated that with the variation in reaction conditions the mechanistic course of the reaction changes leading to different products. The electronic structures of the reactants, transition states and final products off the reactions have been investigated on the basis of AM1 and PM3 methods.
