Abstract
The synthesis of two previously unknown polycyclic ring systems, benzo [h]naphtho[1'2':4,5]thieno[2,3-c]quinoline (1) and ':4,5]thieno[2,3-c] [1,2,4]triazolo[4,3-a]quinoline (2), was achieved via oxidative photoc yclization of -(1-naphthyl)naphtho[2,1-b]thiophene-2-carboxamide (5). The total assignment of their H-1 and C-13 nmr spectra was determined by the concerted use of two-dimensional nmr methods.
