Regio- and stereoselectivity of the 1,3-dipolar cycloaddition of azomethine ylides to 3-nitro-2(1H)-quinolinone derivatives: A new synthesis of Pyrrolo[3,4-c] quinolines
1,3-Dipolarcycloadditions of different azomethine ylides to 3-nitro-2(1H)-quinolinones were carried out to give 3a-nitro-4-oxo-1,2,3,3a,5,9b-hexahydropyrrolo[3,4-c]quinoline-4-one derivatives in satisfactory yield, in most cases with excellent stereoselectivity. The structure and stereochemistry of cycloadducts were studied in detail by X-ray and NMR spectroscopy methods.
将不同的偶氮甲碱叶立德与 3-nitro-2(1H)-quinolinones 进行 1,3-偶极环加成,得到 3a-nitro-4-oxo-1,2,3,3a,5,9 b -hexahydropyrrolo[3 ,4-c]喹啉-4-酮衍生物的收率令人满意,在大多数情况下具有优异的立体选择性。通过X射线和核磁共振光谱方法详细研究了环加合物的结构和立体化学。
