New Routes to Phenalenones from 2,7-Dihydroxynaphthalene. X-Ray Crystal Structure of 4-(α-Hydroxybenzyl)-2-phenyl-6H-phenaleno-pyran-6-one

9-Aryl-6-hydroxy-1H-phenalen-1-ones and 2-aryl-4-aroyl-6H-phenalenopyran-6-ones can be obtained by the reaction of 2,7-dihydroxyphenalene-1-carbaldehyde with acetophenones and by condensation of aroylacetaldehydes with 2,7-dihydroxynaphthalene under acid conditions.Aroylacetaldehydes may be involved in the former reaction also, arising by transfer of the formyl group from the naphthaldehyde to the acetophenone. 2,7-Dihydroxynaphthalene-1-carbaldehyde reacts with 2-hydroxyacetophenone to form 1H-naphthoxanthen-1-one.Interaction of naphthalene-2,7-dioxybismagnesium dibromide with cinnamaldehydes affords 4-benzyl-2-phenyl-6H-phenalenopyran-6-ones.
