C 4 ‐C 5 periannulation of 1‐naphthols and ynones via BF 3 . Et 2 O mediated one‐pot cascade under metal and solvent‐free conditions have been developed for the synthesis of perinaphthenones. Furthermore, this strategy features the formation of new periannulation at C 4 ‐C 5 positions of α ‐naphthol, synthesis of highly substituted perinaphthenones, broad substrate scope, readily available starting materials and good to moderate yields. The perinaphthenones products synthesized here have exhibited interesting photo physical properties
