  Application of intramolecular cycloaddition/retro cycloaddition reactions for the synthesis of unsymmetrical 2,2′-bipyridine and 2-benzofuropyrazin-2-ylpyridine analogues

  摘要：

  1,2,4-Triazines bearing cycloalkeno[c]pyridine substituents at the 5-position, 2a-d, prepared by an intermolecular Diels-Alder reaction of bi-5,5-triazines with cyclic enamines, were provided with an alkynyloxy or a 2-cyanophenoxy group at the 3-position of the triazinyl unit. A subsequent intramolecular Diels-Alder reaction of the former, followed by loss of N-2 leads to two new classes of 2,2'-bipyridine analogues containing different heterocyclic units, namely cycloalkeno[c]pyridine and 2,3-dihydrofuro- or 2,3-dihydropyrano[2,3-b]pyridine 8a-h; the intramolecular reaction of the 2-cyanophenoxy compound gives benzo[4,5]furo[2,3-b]pyrazine 10a-c.
