## Abstract Several ethyl 3β[(3βarylβ4βmethyl)β2(1__H__)βpyrrolyl]β4βmethylβ1__H__βpyrroleβ2βcarboxylates have been synthesized using two successive ethyl isocyanide additionβcyclizations to the appropriate nitropropene derivatives.
The new heteroaromatic compounds, dipyridotetraazapentalenes 3-5, were synthesized in two steps from readily available triazolopyridines 6 and 10. N-Arylation of 6 and 10 followed by subsequent reductive cyclization of the N-(nitropyridyl)-triazolopyridines with triethylphosphite in toluene afforded
