  • Patent number: 5808120
    Abstract: A method of synthesizing 9-cis-retinoic acid, all-trans-retinoic acid or 9-nor-retinoic acid is disclosed. The method comprises the steps of adding a Grignard reagent of ##STR1## to 2,2,6 trimethyl cyclohexanone is disclosed. R is a methyl group or H and the CH.sub.2 --OH group is in either the cis or trans orientation relative to the HC.tbd.C- group. The resulting product is converted into retinoic acid. In the preferable form of the present invention, a tritium-labelled retinoic acid is synthesized, wherein the labelling is at the C.sub.20 position. A preparation of tritium-labelled 9-cis-retinoic acid with a specific activity of greater than 65 Ci/mmol is also enclosed. In a most preferred embodiment, the specific activity is greater than 75 Ci/mmol.
