An Expeditious Synthesis of 1,2,3,4-Tetrahydro-1,1-dimethylphenanthrenes

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.
