  • Patent number: 7388098
    Abstract: Provided is a dynamic resolution method of enriching a desired isomer of an alpha-substituted carboxylic acid relative to an undesired isomer, the method comprising: (a) in a solvent, contacting the alpha-substituted carboxylic acid, wherein the alpha substitution is with a leaving group and wherein the alpha carbon is chiral, with a homochiral amine to form a salt that is partially insoluble under selected reaction conditions, wherein the homochiral amine is selected so that the solubility of the amine salt of the undesired alpha-substituted carboxylic acid is greater than that of the amine salt of the desired alpha-substituted carboxylic acid under the selected reaction conditions; (b) reacting under the selected reaction conditions the salt with a nucleophile, wherein the reacting is effective in producing a net increase in the less soluble amine salt of the alpha-substituted carboxylic acid, and wherein the selected conditions are selected to (i) promote nucleophilic substitution of the nucleophile and th
