1',2',3',4'-Tetrahydrospiro (2a) and its 7'-methyl (2b), 5',8'-dimethyl (2c) and 6',7'-cyclohexeno (2d) derivatives have been synthesized starting from the anhydride of indane-2-carboxy-2-acetic acid and appropriate aromatic hydrocarbons.These spiranes when dehydrogenated using 10percent Pd-C as catalyst, underwent smooth rearrangement giving benzanthracene (7a), 2-methylbenzanthracene (7b), 1,4-dimethylbenzanthracene (7c) and pentaphene (7d) respectively.
