  • Publication number: 20030181729
    Abstract: The object of the present invention is to produce a 5-alkyl-oxazolidin-2,4-dione by an industrially advantageous method. The invention relates to novel process for producing a high-purity 5-alkyl-oxazolidin-2,4-dione comprising the steps of reacting a 2-hydroxycarboxylic acid amide with a carbonic acid ester in the presence of a metal alcoholate, thereby completing the reaction in one step, and then isolating the reaction product by a neutralization crystallization method.

  • Patent number: 6562967
    Abstract: One aspect of the present invention relates to a method for the kinetic resolution of racemic and diastereomeric mixtures of chiral compounds. The critical elements of the method are: a non-racemic chiral tertiary-amine-containing catalyst; a racemic or diastereomeric mixture of a chiral substrate, e.g., a cyclic carbonate or cyclic carbamate; and a nucleophile, e.g., an alcohol, amine or thiol. A preferred embodiment of the present invention relates to a method for achieving the kinetic resolution of racemic and diastereomeric mixtures of derivatives of &agr;- and &bgr;-amino, hydroxy, and thio carboxylic acids. In certain embodiments, the methods of the present invention achieve dynamic kinetic resolution of a racemic or diastereomeric mixture of a substrate, i.e.
