Abstract
The synthesis of two previously unknown heterocyclic ring systems, nam ely benzo[h]naphtho[2',1':4,5]thieno[2,3-c]quinoline (1) and benzo[f]n aphtho[2',1':4,5]thieno[2,3-c]quinoline (2) was accomplished via photo cyclization of the appropriate amides followed by chlorination and cat alytic dechlorination. The total assignment of H-1 and C-13 nmr spectr a of 2 was determined utilizing two-dimensional nmr methods, providing unequivocal structural proof of the two novel polycyclic ring systems .
