Abstract

A process for the preparation of disubstituted adamantine derivatives characterized by the factor that the aromatic receptors can be a series of halide anisole, phenol, toluene, naphthalene, thiophene, or furan and their substituted derivatives. The synthesized disubstituted adamantine derivatives were subsequently converted into a new class of synthetic retinoids of pharmaceutical importance.
