    Abstract: This invention relates to certain dendrimer compounds. In particular, this invention relates to novel dendrimer compounds that can be elaborated to give increasingly large and complex compounds. These elaborated compounds can be attached to, or can encapsulate within, active agent(s) so as to beneficially modify the characteristics of that active agent. Alternatively, the elaborated compounds can themselves be beneficially modified into therapeutic agents by the attachment of inactive agents.

    Abstract: The problem to be solved by the present invention is to ea lily and efficiently produce an amino acid having 2 to 7 carbon atoms as a high-purity solid without complicated operation, which is useful as a synthetic intermediate for medicines or agrochemicals.The present invention is characterized in comprising a step of precipitating solid amino acid with high purity. In the present invention, the by-produced salt composed of the sulfonic acid and the amine was removed to the mother liquor by reacting an amine with a sulfonic acid salt of amino acid in an aprotic polar solvent, or by reacting a sulfonic acid with an amine salt of amino acid in an aprotic polar solvent.The sulfonic acid salt of amino acid, for example, may be produced by reacting a N-(tert-butoxycarbonyl) amino acid with a sulfonic acid, or by reacting an amino acid tert-butyl ester with a sulfonic acid.
