Isoxazolo[5,4-d]pyrimidine-4,6(5H,7H) diones 2a-2f have been synthesized from the reaction of ethyl 5-amino-3-methyl-4-isoxazole carboxylate(1) with aryl isocyanates in the presence of keggin heteropolyacid H3[PW12O40] as a green solid acid catalyst at room temperature in a one-pot process in good yields.
