Selective Electrophilic Cyclization of ortho-Carbonylarylacetylenols for the Synthesis of Cyclopenta[a]naphthalenol and 2-phenylnaphthalen-1-ol Analogs

Synthesis of cyclopenta[ a ]naphthalenols and 2-phenylnaphthalen-1-ols via selective electrophilic cyclization using o- carbonylarylacetylenols is reported. Selectivity can be controlled using different acids and solvents to give a variety of products.
