  • Patent number: 7282605
    Abstract: The present invention provides a process for producing an optically active 2-allylcarboxylic acid derivative, which is useful as a pharmaceutical intermediate, from readily available and inexpensive starting materials by the process which can be practiced on a commercial scale in a simple and easy manner, and certain 2-allylcarboxamide derivatives, which are novel and important intermediates in that process. An N-allylcarboxamide derivative undergoes rearrangement reaction diastereoselectively in the presence of a base to give a 2-allylcarboxamide derivative, the resulting derivative is subjected to a carbamation reaction and solvolysis to give an optically active 2-allylcarboxylic acid ester, and then the ester obtained is stereoselectively hydrolyzed using an enzyme to produce 2-allylcarboxylic acid having a high optical purity. In addition, the present invention provides a 2-allylcarboxamide derivative compound which is a novel intermediate in the process of the present invention.

  • 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.

  • Patent number: 6541644
    Abstract: Processes for isolating substantially pure natural L-&bgr;-3-indolylalanine (L-&bgr;-3) from a mixture of amino acids, such as a protein hydrolysate. A protein hydrolysate, for example of casein or soy protein, is passed over a polymeric resin attractive to aromatic amino acids but not attractive to aliphatic amino acids. The aromatic amino acids are retained on the resin while the aliphatic amino acids pass over the resin and are collected. The resin is then washed to displace any residual aliphatic acids which may be physically associated with but not bound to the resin. Thereafter, the resin is eluted with a dilute acid to displace L-phenylalanine and L-tyrosine and provide a solution thereof while allowing L-&bgr;-3 to be retained on the resin. The resin is then further eluted with a dilute base to displace L-&bgr;-3 from the resin and provide a solution of L-&bgr;-3. Substantially pure natural L-&bgr;-3 is recoverable from this solution.
