An efficient silver‐mediated coupling of aniline with ene carbonyl/acetylenic carbonyl compounds for the synthesis of quinolines is reported. The transformation is effective for a broad range of substrates, thus enabling the expansion of substituent architectures on the heterocyclic framework. The electronic properties of the substituents on the amine have been investigated. It was found that molecules

activation/cyclization of simple, cheap, and easily available anilines with alkynes for direct and highly efficient synthesis of privileged quinolines with exclusive regioselectivity and broad substrate/functional group tolerance and in good to excellent yields, where DMSO was employed as both the solvent and the C1 building block of quinoline products, is reported. Mechanistic experiments revealed that

We herein disclose a novel Co(III)-catalyzed C–H activation/carbonylation/cyclization of anilines with ketones using paraformaldehyde as the carbonyl source, giving direct access to diverse quinolines with broad functional group tolerance and in good to excellent yields. Moreover, exclusive site-/region-selectivity was observed in this versatile transformation.
Quinoline Synthesis: Three component reaction of aniline, alkynes, and formaldehyde under microwave irradiation promoted by CSA led to the formation of 4‐arylated quinolines via Povarov type reaction.

A palladium-catalyzed annulation of ortho-vinylanilines with dimethylsulfoxide was developed to access 4-aryl quinolines in moderate to good yields. Activated by 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) adduct (DABSO), DMSO served as a “CH–” fragment in this transformation. It represents a facile pathway leading to 4-aryl quinolines.
