Abstract
The synthesis of five novel polycyclic heterocyclic ring systems via p hotocyclization is reported. These are [1]benzothieno[3',2':4,5]thieno [2,3-c]quinoline (1), no[3',2':4,5]thieno[2,3-c][1,2,4]triazolo[4,3-a] ?? quinoline (2), o[3',2':4,5]thieno[2,3-c]tetrazolo[1,5-a]quinoline ( 3), thieno ':4,5]thieno[2,3-c][1,2,4]triazolo[4,3-a]quinoline (4), and [3',2':4,5]thieno[2,3-c]tetrazolo[1,5-a]-quinoline (5). The total ass ignments of the H-1 and C-13 nmr spectra of 1, 4, 5, and 15 were deter mined by utilizing two-dimensional nmr methods.
