Abstract
Benzo[h]naphtho[1',2':4,5]thieno[2,3-c][1,6]naphthyridine, a novel poly- cyclic heterocyclic ring system, has been synthesized as the 14-methyl derivative (8) in four steps from known intermediates. The structure of (8) is supported by assignment of the proton and the protonated carbon atoms by 2D-nmr techniques (COSY and a carbon-hydrogen one-bond coupling experiment)
