amine which, in turn, afforded products of nucleophilic substitution on reaction with alkoxymethylene derivatives. Thermal cyclization of selected alkoxymethylene derivatives yielded substituted pyridoquinoxalines. The conditions for successful hydrolysis of ester, decarboxylation of the acid, following chlorination of pyridone and reductive removal of the chlorine atom from it to produce parental heterocycle
5-硝基-2,3-二苯基喹喔啉的催化加氢反应生成相应的胺,该胺在与烷氧基亚甲基衍生物反应时又提供亲核取代的产物。所选烷氧基亚甲基衍生物的热环化产生取代的吡啶并喹喔啉。发现了成功水解酯,酸脱羧,吡啶酮氯化后以及从中还原除去氯原子以产生亲代杂环2,3-二苯基-吡啶并[2,3- f ]喹喔啉的条件。亲核取代的所有测试产物均未显示抗菌活性。
