Several new α‐alkoxy‐ and α‐hydroxyphosphonate derivatives of tetrazole‐quinolines were synthesized from the reaction of 2‐azidoquinolines 3‐carboxaldehyde 1a,b with trialkyl phosphites and dialkyl phosphites. On the other hand, azaphospholes 12a,b were obtained by treating 1a,b with tris(dimethylamino)phosphine. Furthermore, Perkin‐type condensation of 1a,b and tetraethyl methylenebisphosphonate provided
由2-叠氮喹啉3-甲醛1a,b与亚磷酸三烷基酯和亚磷酸二烷基酯的反应合成了四唑-喹啉的几种新的α-烷氧基和α-羟基膦酸酯衍生物。另一方面,通过用三(二甲基氨基)膦处理1a,b获得氮杂磷酯12a,b。此外,1a,b和亚甲基双膦酸四乙酯的Perkin型缩合反应提供了相应的基于四唑并喹啉的双膦酸酯14a,b。根据预测结果(PASS程序),在体内确定了所制备化合物的抗炎活性由急性角叉菜胶诱导的大鼠足水肿引起。许多新化合物以50 mg / kg体重的剂量表现出显着的抗炎特性。与吲哚美辛相比,尤其是14a和14b表现出显着的活性,吲哚美辛在本研究中用作参考标准。
