Various N-heteroaromatic compounds, including pyridines, quinolines and isoquinoline, react with arynes and nitrile-containing solvents to give N-arylated 1,2-dihydro-2-pyridinyl, -2-quinolinyl and -1-isoquinolinyl nitriles in excellent yields.
A series of novel 11b-substituted 1,6,7,11b-tetrahydropyrimido[6,1-a]- isoquinoline-2,4-diones and 4-thioxo-1,3,4,6,7,11b-hexahydropyrimido[6,1-a]isoquinolin-2- ones were synthesized, utilizing two alternative strategies for ring closure of tetrahydroisoquinoline intermediates obtained from N-phenethyl enaminones.
[reaction: see text] Palladium-catalyzed intramolecular carbon-carbon bond formation of aryl halides and amide-enolates gave 4-arylisoquinoline derivatives in good yields, which were further converted into the isoquinoline alkaloids cherylline and latifine.
A one-pot Yb(III)-mediated cascade reaction has been developed leading to small molecules based on a novel structural motif, i.e. quinazolin-4-one moiety fused with an isoquinoline ring, for potential inhibition of TNF-α.
A copper-catalyzed synthesis of 2-(aminomethyl)indole through domino three-component coupling-cyclization has been developed. This reaction proceeds through Mannich-type coupling of 2-ethynylanilines, aldehydes, and secondary amines, followed by hydroamination. This indole formation was applicable to the synthesis of 4-methylene-2,3,4,9-tetrahyro-1H-pyrido[3,4-b]indoles and 5,6,7,8-tetrahydrobe...
A facile synthetic method to access 3-substituted isoquinoline or dihydroisoquinoline derivatives has been developed via a novel cyclization reaction of N-sulfonyl-1,2,3-triazole derivatives by thermally induced rearrangement.
