The present invention pertains to Benzyl-substituted tetracyclic heterocyclic compounds, as well as the resulting pharmaceutical compositions, and their use in the treatment or prophylaxis of diseases alleviated by inhibition of type 5 phosphodiesterases. Furthermore, the present invention pertains to the methods of manufacturing these Benzyl-substituted tetracyclic heterocyclic compounds.
N‐Heterocycliccarbene‐catalyzed reactions of indolin‐3‐ones with 2‐bromoenals opened an asymmetric access to 3,4‐dihydropyrano[3,2‐b]indol‐2(5 H)‐ones in good yields and with good to excellent enantioselectivities. This protocol tolerates a broad substrate scope. In addition, a possible mechanism for the annulation reaction is presented.

developed an organocatalyzed three-component reaction of 1-acetylindolin-3-ones, β,γ-unsaturatedα-ketoesters and amines, which provide an efficient approach to access polysubstituted 1H-pyrido[3,2-b]indoles. Under the catalysis of 4-methylbenzenesulfonic acid monohydrate, the reactions of a wide range of 1-acetylindolin-3-ones, β,γ-unsaturatedα-ketoesters and amines took place smoothly to generate
我们已经开发了有机物催化的1-乙酰吲哚-3-酮,β,γ-不饱和α-酮酸酯和胺的三组分反应,这为获得多取代的1 H-吡啶并[3,2- b ]吲哚提供了一种有效的方法。在4-甲基苯磺酸一水合物的催化下,各种1-乙酰吲哚-3-酮,β,γ-不饱和α-酮酸酯和胺类的反应顺利进行,生成相应的稠密取代的1 H-吡啶基[3]。在温和的反应条件下,2-2- b ]吲哚衍生物的收率可以接受。另外,以良好的产率实现了代表性产物向生物学上重要的δ-碳卤化物的进一步转化。

Asymmetric Michael addition of 1-acetylindolin-3-ones to β,γ-unsaturatedα-ketoesters was investigated for the synthesis of chiral indolin-3-ones with two adjacent tertiary stereogenic centers. Under the catalysis of a chiral bifunctional squaramide derived from l-tert-leucine, a wide range of 1-acetylindolin-3-ones and β,γ-unsaturatedα-ketoesters were well-tolerated in this transformation to provide
