Ila Iron(III)-Catalysed Povarov Cyclisation for the Synthesis of Fused Dibenzo[b,f][1,7]naphthyridine Embedded Arylpyrrolo Scaffolds Authors Raj Kamal Sahoo Gopal Rana Abhishek Kar Sourav Ghosh Umasish Jana ∗ Artikel empfehlen Abstract Artikel einzeln kaufen(opens in new window) Alle Artikel dieser Rubrik(opens in new window) Abstract An FeCl3-catalyzed Povarov reaction for the efficient synthesis of dibenzo[b,f][1,7]naphthyridines utilizing 1-(2-alkynylaryl)-2-pyrrolecarbaldehydes and arylamines in excellent yields is demonstrated. The essential features of the present strategy are easy preparation of substrates, broad substrate scope, mild reaction conditions, and high atom economy and yields, in the presence of environmentally friendly iron catalysis. Key words Key wordsarylpyrrolecarbaldehydes - phosphorus oxychloride - arylamines - 1,7-naphthyridines - ferric chloride Volltext Referenzen References 1 Kerru N, Gummidi L, Maddila S, Gangu KK, Jonnalagadda SB.
