The ketoesters 3 and 4, obtained by the condensation of 2-cyclohexanone carboxylate and 1-chloro-3-pentanone, were heated with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) to yield the dienones 5 and 6, which on hydrolysis with potassium t-butoxide and dimethyl sulfoxide afforded tetralin 8. These were converted to tetralone 10 by methylation and oxidation respectively. Further methylation of 10 yielded tetralone 11.
