    • Abstract


      Synthetically useful substituted hexahydrobenzofluoren-11-ones and tetrahydropentalenonaphthalen-10(H)-ones are prepared in one step by the reaction of cyclic α, β-unsaturated acids, namely, 1-cyclohexene.-1-carboxylic acid and 1-cyclopentene-1-carboxylic acid, with substituted dialkoxynaphthalenes in the presence of polyphosphoric acid. The stereochemistry at the C/D ring junction is determined from the1H NMR and by decoupling experiments.
