| Abstract: | 7-Methoxy-6-methyl-1-tetralone 6 on Wolff-Kishner reduction followed by chromic acid oxidation furnishes tetralone 8 which on Grignard reaction with isopropylmagnesium iodide yields 6-methoxy-7-methyl-1-isopropyltetralol 9. The tetralol 9 on hydrogenation over Pd-C gives 7-methoxynorcalamenene 1. The tetralone 6 on reaction with methylmagnesium iodide followed by hydrogenation over Pd-C affords tetralin 12. The chromic acid oxidation of 12 furnishes 4,7-dimethyl-6-methoxytetralone 2. The telralone 2 on Grignard reaction with isopropylmagnesium iodide yields tetralol 13 which on hydrogenation over Pd-C affords(±) -7-methoxycalamenene 3. |
