The synthesis of novel polycyclic heterocyclic ring systems via photocyclization. 8 . [1]Benzothieno[2,3-c]naphtho[1,2-h]quinoline and [1]benzothieno[2,3-c]naphtho[1,2-h][1,2,4]triazolo[4,3-a]quinoline

The previously unknown polycyclic heterocyclic ring systems, namely, 1]benzothieno2,3-c]naphtho1,2-h]-quinoline and 1]benzothieno2,3-c]naphtho1,2-h]1,2,4]triazolo4,3-a]quinoline were synthesized via photocyclization of 3-chloro-N-(1′-phenanthryl)benzob]thiophene-2-carboxamide.
