Photocyclization of 3‐chloro‐ N ‐(9‐phenanthryl)benzo[ b ]‐thiophene‐2‐carboxamide ( 3 ) and 3‐chloro‐ N ‐(9‐phenanthryl)‐naphtho[1,2‐ b ]thiophene‐2‐carboxamide ( 10 ) yielded dibenzo[ f,h ]benzothieno[2,3‐ c ]‐quinolin‐10(9 H )‐one ( 4 ) and dibenzo[ f,h ]naphtho[2′,1′:4,5]thieno[2,3‐ c ]quinolin‐10(9 H )‐one ( 11 ), respectively. Further elaboration of the lactams provided three novel unsubstituted new ring systems.
