Abstract
We report the synthesis of orthogonally functionalized naphthalenes from simple, commercially available indanones in four steps. The developed method proceeds through a two-step process that features a thermally induced fragmentation of a cyclopropane indanone with simultaneous 1,2-chloride shift. Migration of the chloride substituent occurs in a regioselective manner to preferentially afford the para-chloronaphthol substitution pattern. The obtained naphthols are versatile building blocks that can be selectively modified and used for the efficient construction of biologically active molecules. This has enabled the total synthesis of the potent anticancer natural product chartarin through a highly convergent retrosynthetic bond disconnection.

Abstract
A new version of benzannulation featuring the use of aromatic tert-butyl ynol ethers as the convenient precursors for arylketenes has been developed. Both ynamides and ynol ethers undergo this reaction smoothly, giving 3-amino and 3-alkoxy 1-naphthols in good to excellent yields under the heated reaction conditions. The high efficiency, excellent regioselectivity, good functional group compatibility, and broad substrate scope render this reaction particularly valuable for organic synthesis.

Abstract
Described is the development of a highly efficient 2π disrotatory ring-opening aromatization sequence using bicyclo[3.1.0]hexan-2-ones. This unprecedented transformation efficiently proceeds under thermal conditions and allows facile construction of uniquely substituted and polyfunctionalized benzoates. In the presence of either amines or alcohols formation of substituted anilines or ethers, respectively, is achieved. Additionally, the utility of this method was demonstrated in a short synthesis of sekikaic acid methyl ester.
