Pechmann condensation of β-naphthol with ethyl acetoacetate in the presence of anhydrous aluminium chloride gives, besides two known compounds, 4-methyl-6,7-benzocoumarin and 3-methyl-9-hydroxyphenalen-1-one (I).The Duff reaction of β-naphthol gives the new compounds 1,3-diformyl-2-naphthol and 2-formyl-2,3-dihydro-1H-naphth-oxazine (II) and the known 2,2'-dihydroxy-1,1'-binaphthylmethane.Compound (II) exists as a mixture of rotamers.
