Catalytic dehydrogenation of l-isopropyl-8, 9-benzospiro [ 5, 5] undecane-7-ol ( 5) has been carried out to study the effect of isopropyl group on the spirocyclohexane ring during the ring transformation of the spiro [ 5, 5] system. The dehydrogenation of 5 gave 1-isopropylphenanthrene as the main product. For the synthesis of 5, the anhydride of l-carboxy- 2-isopropylcyclohexane-l-acetic acid (1) was condensed with benzene to give the single ketoacid 2 which was reduced catalytically to 3. Intramolecular acylation of the acid chloride of 3 gave the spiroketone 4 which was reduced to 5. [ABSTRACT FROM AUTHOR] |
