describe a new one-pot method to synthesize 4,7-substituted pyrrolo[1,2-a]quinoxalines and related heterocyles through a cascade of redox reactions/imine formation/intramolecular cyclization. This procedure tolerates readily available substituted 1-(2-nitrophenyl)pyrrole derivatives and aliphatic or benzylic alcohols as starting materials using iron powder and acidic conditions. This is the first example
在这里,我们描述了一种新的一锅法,通过级联的氧化还原反应/亚胺形成/分子内环化反应来合成4,7-取代的吡咯并[1,2- a ]喹喔啉和相关杂环。该方法耐受使用铁粉和酸性条件容易获得的取代的1-(2-硝基苯基)吡咯衍生物和脂族或苄基醇作为起始原料。这是在一个罐中通过铁介导的芳基硝基还原和酒精的好氧氧化构造N-杂环的第一个例子。
