The invention relates to a silane or silane mixture obtainable by reacting a hydrolysable silane of the formula (A): SiR4 in which R is a hydrolytically condensable group or hydroxyl with a compound R*(OH)x where x is 1, 2, 3 or greater 3, where R* has a straight-chain or branched hydrocarbon skeleton which, according to the number x, is monovalent, divalent, trivalent or multivalent, and has a hydrocarbonaceous chain interrupted by at least two —C(O)O— groups, wherein there are a maximum of 8 successive carbon atoms in the individual hydrocarbon units formed by interruptions within this chain and the, or in the case of branched structures at least one, end of the hydrocarbonaceous chain at the opposite end to the sole hydroxyl group or one of the hydroxyl groups bears an organically polymerizable group, wherein the alcohol is otherwise unsubstituted or has further substituents. The invention further relates to an organically modified silica polycondensate formed as a result of hydrolytic condensation of the silane or silane mixture and optionally a subsequent organic polymerization of the organically polymerizable groups, with optional addition of an organic, at least difunctional compound to the silica polycondensate prior to the organic polymerization.

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.
