derivatives 13a–d to afford the arylidene exchange derivatives 14a–c and the pyranopyrazole derivative 15, respectively. The arylidene derivatives 10a, b react also with indane‐1,3‐dione 16 to afford the arylidene exchange derivatives 18a, b. The molluscicidalactivity of the synthesized compounds towards Biomphalaria alexandrina snails, the intermediate host of Schistosoma mansoni, was investigated and most
