摘要：

Four previously unknown polycyclic heterocyclic ring systems, namely, benzo[h]thieno[3',2':4, 5]thieno[2,3-c]quinoline (6), benzo[h]thieno[3',2':4,5]thieno[2,3-c]quinoline (11), benzo[f]thieno[3',2':4,5] thieno[2,3-c] tetrazolo[1,5-a]quinoline (12) and benzo[f]thieno [3',2':4,5] thieno[2,3-c][1,2,4] triazolo[4,3-a]quinoline (13), were synthesized via oxidative photocyclization. Unequivocal total assignments of the proton and carbon nmr spectra of 6 and 11 were made through the concerted usage of COSY, HMQC and HMBC two-dimensional nmr spectroscopic methods.
