The reaction of 3-aroylpyrrolo[1,2-c][4,1]benzoxazepine-1,2,4-triones with urea and thiourea leads to the formation of 9-aroyl-8-hydroxy-6-[2-(hydroxymethyl)phenyl]-1,3.6-triazaspiro[4.4]-non-8-ene-2,4,7-triones and 9-aroyl-8-hyclroxy-6-[2-(hydroxymethyl)phenyl]-2-thioxo-1,3,6-triazaspiro[4.4]non-8-ene-4,7-diones, respectively. The described reaction is a convenient method for the synthesis of the hardly accessible 1.3.6-triazaspiro[4.4]nonenone system (hydantoins spiro-annulated to the pyrrole ring).
