Complete assignment of the 1h‐ and 13c‐nmr spectra of [1]benzothieno[2,3‐c]naphtho[1,2‐h]quinoline and [1]benzothieno[2,3‐c]naphtho[1,2‐h][1,2,4]triazolo[4,3‐a]quinoline. Concerted use of two‐dimensional nmr techniques

The 1H‐ and 13C‐nmr spectra of [1]benzothieno[2,3‐c]naphtho[1,2‐h]quinoline and [1]benzothieno[2,3‐c]‐naphtho[1,2‐h][1,2,4]triazolo[4,3‐a]quinoline were totally assigned using a combination of two‐dimensional nmr techniques. After correlation of the proton signals by a COSY spectrum and one‐bond heteronuclear correlation, complete assignment of the 1H‐ and 13C‐nmr spectra of the novel heterocyclic compounds required the application of long‐range CH coupling information particularly for quarternary resonance assignments and the orientations of individual spin systems relative to one another.
