2-di(carboxymethyl)-1-phenylcyclohexane. A two stage cyclisation of this diacid via intramolecular acylation gave 9,10-benzobicyclo[5.3. 2.01,6]dodecan-8,12-dione as an attractive precursor of the morphinan ring system. Alternatively, the foregoing diacid could be cyclised to phenylbicyclo[4,3,0]nonan-8-one which was converted into 2-methyl-4a-phenyl-trans-decahydroisoquinoline.
