-butoxide and diethyl chlorophosphate to afford an intermediate dihydropyrido[2,3- b ]pyrazin-2-ylphosphate derivative which in turn furnished the desired 1,2,4-oxadiazolylimidazo[1,5- a ]pyrido[2,3- e ]pyrazine derivatives with 5-alkyl-3-isocyanomethyl-1,2,4-oxadiazoles in the presence of additional tert -butoxide. The title compounds are potential ligands for the γ-aminobutyric acid A/benzodiazepine receptor
从2-氯-3-硝基吡啶开始,合成2-异丙基-1,4-二氢吡啶并[2,3 - b ]吡嗪-2( 3H ),3-二酮。将该化合物与 叔 丁醇钾和氯代磷酸二乙酯反应, 得到中间体二氢吡啶并[2,3 - b ]吡嗪-2-基磷酸酯衍生物,进而提供所需的1,2,4-恶二唑基咪唑并[1,5- a ]在另外的 叔 丁醇盐存在下,将吡啶并[2,3- e ]吡嗪衍生物与5-烷基-3-异氰基甲基-1,2,4-恶二唑合成 。标题化合物是γ-氨基丁酸A /苯并二氮杂receptor受体复合物的潜在配体。
