The Synthesis of Novel Polycyclic Heterocyclic Ring Systems via Photocyclization. 7. Benzothienonaphthoquinoline and Benzothienonaphthotriazoloquinoline

The synthesis of two novel polycyclic heterocyclic ring systems via photocyclization is described.These are benzothienonaphthoquinoline and benzothienonaphthotriazoloquinoline.In the 1H nmr spectrum the proton at position 6 is strongly deshielded in the first ring system while the proton at position 6 in the second ring system is shifted considerably upfield while the proton at position 8 in the second ring system is the most deshielded proton in that ring system.The bay regions in both ring systems are severely congested.
