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