A brief and convergent synthetic route to defucogilvocarcin M chromophore: The formal synthesis of WS-5995 A and C

Densely substituted styryl sulfone 20 is shown to undergo double annulation with phthalide 21 to give, in one-pot operation and in excellent yield, the benzonaphthopyranone scaffold 22 of gilvocarcins.

Photochromic benzopyrano-fused naphthopyrans

Described are novel photochromic benzopyrano-fused naphthopyran compounds, examples of which are naphthopyran compounds having a substituted or unsubstituted benzopyran group fused to one side of the naphtho portion of the naphthopyran and having certain substituents at the position ortho to the oxygen atom of the naphthopyran ring. These compounds may be represented by the following: Also described are polymeric organic host materials that contain or that are coated with such compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, benzopyrans, and spiro(indoline)type compounds.
