Abstract
2H-4,8-Dimethylthieno[2′,3′:5,6]naphtho[1,2-b]pyran-2-one (7), a potential photobiological agent, was synthesized in six steps starting from commercially available 1,5-naphthalenediol. A Newman-Kwart rearrangement of naphthopyrone 2 and an unusual S-Claisen rearrangement of naphthopyrone 5 are the key steps. The structures of 7 and its precursors were fully characterized.
