Synthesis and total 1H-NMR assignment of [1]benzothieno-[2,3-c] [1,10] phenanthroline

Article abstract of DOI:10.1002/jhet.5570330334

The synthesis of [1]benzothieno[2,3-c][l,10]phenanthroline (5) is described. It was obtained in four steps from known starting materials. The basic skeleton of the molecule and of the phenanthroline ring were formed via photocyclization. The total assignment of ¹H-nmr spectra was accomplished with the aid of two-dimensional nmr methods.
