A solid phase synthetic method for preparing arylretinamides is provided.
The method comprises reacting hexachloroacetone with a solvent-suspended
resin-bound triphenylphosphine to provide a suspension comprising an
activated chlorinating reagent; reacting retinoic acid with the activated
chlorinating reagent to provide retinoyl chloride; adding pyridine and a
select arylamine to the resulting mixture; and stirring the resulting
mixture for a time and at a temperature sufficient for the select
arylamine to react with the retinoyl chloride and provide the
arylretinamide. Also provided, are select arylretinamides that can be
prepared by the present method, and methods of using such arylretinamides
to induce apoptosis in cancer cells.
