A green process to access pyrazolo-fused 4-azafluorenones (indeno[1,2- b ]pyrazolo[4,3- e ]pyridines, IPP) 4a-x via the three-component reaction between indan-1,3-dione ( 1 ), benzaldehydes 2 and 5-amino-1-arylpyrazoles 3 is described. These compounds were successfully used as precursors of the nove...
