Let me attract your attention to the paper
(by a coincidence, I had this paper in hands when reading your post):

Nicolaou, K.C.; Snyder, S.A. Chasing molecules that were never there … Angew. Chem. Int. Ed. 2005, 44, 1012-1044.

The authors dedicated 3+ pages of this excellent paper (which concerns structure mis-assignments and the role of total synthesis) to the title molecule: “Case study 1: Diazonamide A”, pp. 1030-1033.
You may see there both the incorrect structures and the correct one (which is ’69′ in paper’s numbering), along with the detailed comments.
