N2 - A simple convergent and general method has been developed for the synthesis of 1,2,3,4-tetrahydro-1,1-dimethylphenanthrenes 4a-f and a few 1,2,3,4,9,10-hexahydro-1,1-dimethylphenanthrenes 5c-f by polyphosphoric acid catalysed reaction of the easily accessible 2-(2-arylethyl)-3,3- dimethylcyclohexanones 3a-f. The tetrahydrophenanthrenes 4a,c,e,f have been converted to the respective benzylic ketones 6a,c,e,f by oxidation with pyridinium chlorochromate and Celite.
