C4-C5 periannulation of 1-naphthols and ynones via BF3.Et2O 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 C4-C5 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. (Figure presented.).
