Retinoids that have two functional groups at the side-chain terminus have been synthesized. The two terminal functional groups are combinations of the carboxyl, carbethoxy, and N-(ethylamino)carbonyl groups. The synthesis route is based on the sodium amide catalyzed condensation of (E,E)-beta-ionylideneacetaldehyde
