Ullazines and their π-expanded derivatives have gained much attention as active components in various applications, such organic photovoltaic cells or photosensitizers for CO2 photoreduction. Here, we report the divergent synthesis of functionalized diazaullazines by means two different domino-reactions consisting either a Povarov/cycloisomerization alkyne–carbonyl metathesis/cycloisomerization protocol. The corresponding quinolino-diazaullazine benzoyl-diazaullazine were obtained moderate to good yields. Their optical electronic properties studied compared related, literature-known compounds obtain insights into impact nitrogen doping π-expansion.
