Benzo[a]quinolizine-2-one derivatives are readily assembled from 1,2,3,4-tetrahydroisoquinoline and β-ketoaldehydes by means of a new intramolecular redox-Mannich process. These reactions are promoted by simple acetic acid and are thought to involve azomethine ylides as reactive intermediates.
通过新的分子内氧化还原-曼尼希方法,可以容易地将1,2,3,4-四氢异喹啉和β-酮醛组装成苯并[ a ]喹啉嗪-2-酮衍生物。这些反应通过简单的乙酸促进,并被认为涉及偶氮甲亚胺作为反应性中间体。
