The reaction of ethyl 5-oxo-3-arylamino-2,5-dihydroisoxazole-4-carboxylates with 2-chloropyrimidine and 2-chlorobenzoxazole gave the corresponding isoxazolones with pyrimidine and benzoxazole rings substituted on N-2. Their rearrangements with triethylamine in ethanol produced the corresponding imidazopyrimidine and aminoindole derivatives, respectively, through intramolecular cyclisation. TUeBITAK.
Base-induced rearrangements of N-substituted 3-arylamino-isoxazol-5(2H)- ones to 2-aryl-aminoimidazo[1,2-a]pyridines

, p. 594 - 599 (2013/07/11)
New N-substituted derivatives of 2-substituted 3-phenylamino- and 3-(1-naphthyl)aminoisoxazol-5(2H)-ones were synthesized. The reaction of isoxazolones with 2-chloro-5-nitropyridine gave the corresponding isoxazolones with a nitropyridyl group substituted
