Abstract: 7,8-Dimethyl-1-tetralone <b>4</b> on
sodium borohydride reduction followed by Vilsmeier-Haack reaction furnishes 7,8-dimethyl-3,4-dihydro-2-naphthaldehyde
<b>10</b>. Reduction of <b>10</b> followed by oxidation with Jones reagent
yields 7,8-dimethyl-1,2,3,4-tetrahydro-2-naphthoic acid <b>12</b> which on
treatment with excess of methyllithium affords 7,8-dimethyl-2-(2
-hydroxyisopropyl) tetralin 2. 5,6-dimethyl-1-tetralone <b>5</b> is converted
into the 5,6-dimethyl-2-(2-hydroxyisopropyl)tetralin <b>3</b> by following
similar set of reactions as described above.
