Abstract
The polycyclic heterocyclic compound with a novel ring system, 15-chlo ro[1]benzothieno[2 '',3 '':3',4']-naphtho[1',2':4,5]thieno[2,3-c]quino line was synthesized via photocyclization of o[2',3':3,4]naphtho[2,1-b ]thiophene-2-carboxyamide followed by chlorination with phosphorus oxy chloride. The assignment of its H-1 and C-13 nmr spectra was accomplis hed by utilizing two-dimensional nmr methods.
