Synthesis of spiro[pyrrole-2,5′-thiazoles] by heterocyclization of pyrrolobenzoxazinetriones with salicylaldehyde thiosemicarbazone

3-Aroylpyrrolo[1,2- c ][4,1]benzoxazine-1,2,4-triones reacted with salicylaldehyde thiosemicarbazone to give 9-aroyl-8-hydroxy-2-[2-(2-hydroxybenzylidene)hydrazinylidene]-6-(2-hydroxy-phenyl)-1-thia-3,6-diazaspiro[4.4]non-8-ene-4,7-diones.
