Synthesis of 2,5-bis-arylpyridines by [4 + 2] cycloaddition of 1,4-bis aryl-2-aza-1,3-butadienes with electron-poor dienophiles

, p. 411 - 418 (2000)
Tetrahydropyridines 4a, 4b, 4c and pyridines 7a, 7b, 7c, 9a, 9b, 9c were synthesized by a [4 + 2] cycloaddition between 1,4-bis aryl-2-aza-1,3- butadienes and electron-poor dienophiles. Dimeric cycloadducts 6a, 6b, 6c, were also isolated indicating a competition between the expected Hetero Diels-Alder and a dimerization process.

An oxidative trimerization of three amino acids has been realized to furnish 2,3,5-trisubstuitued pyridines in both cross- and homo-trimerization types. This method is capable of converting simple linear biomass material to heterocycles, which features in
Synthesis of Polysubstituted Imidazoles and Pyridines via Samarium(III) Triflate-Catalyzed [2+2+1] and [4+2] Annulations of Unactivated Aromatic Alkenes with Azides

, p. 3229 - 3241 (2015/11/03)
Samarium(III) triflate-catalyzed [2+2+1] and [4+2] annulations have been identified for the preparation of fully substituted imidazoles and 2,3,5-trisubstituted pyridines from the readily available unactivated aromatic alkenes and azidomethyl aromatics. T
