  Cationic triazinium heterocycles by intramolecular NN bond formation

  摘要：

  Tricyclic heterocycles with a cationic triazinium core were prepared by an intramolecular N-N bond forming reaction of an azine oxime precursor. The azine oxime substrates were prepared by SNAr N-arylation of 2-formylpyrroles followed by oxime formation of the formyl moiety. The synthesis was demonstrated with five different azines and several functional groups. (C) 2014 Elsevier Ltd. All rights reserved.

  The synthesis of 5, 6-dihydro 6-oxo pyrido [2, 3-e] pyrrolo [1, 2-a] pyrazine, and 5, 6-dihydro 6-oxo pyrazino [2, 3-e] pyrrolo [1, 2-a] pyrazine is described. The starting materials, 3-amino pyridine and 3-amino pyrazine are converted into pyrrolyl derivatives using 2, 5-dimethoxytetrahydrofuran in glacial acetic acid. Subsequent cyclizations of these latter afforded the title compounds. Proton nuclear magnetic resonance spectra are studied.
