reflux in acetic acid, these compounds were acetylated to give the cinnoline derivatives 9. The pyrazolones 10a, b react with 3‐furfurylidene‐ and 3‐thienylidene‐malononitrile derivatives 11a, b to afford the pyrano[2,3‐c]pyrazole derivatives 13a–d. These newly synthesized compounds show generally a moderate molluscicidal activity to Biomphalaria alexandrina snails.
2-(3-羟基-5,5-二甲基亚环己基)丙二腈5与芳基重氮盐发生偶氮偶联反应得到3-氨基-2-芳基-6,6-二甲基-8-氧代-2,6,7,8 - 四氢肉啉 - 4 - 腈 7. 在乙酸中回流后,这些化合物被乙酰化得到肉啉衍生物 9. 吡唑啉酮 10a、b 与 3- 糠基-和 3-噻吩基 - 丙二腈衍生物 11a、b 反应得到吡喃并[2,3 - c] 吡唑衍生物 13a - d。这些新合成的化合物通常对 Biomphalaria alexandrina 蜗牛显示出中等的杀软体动物活性。
