  • Publication number: 20060172397
    Abstract: This application discloses a novel process for the conversion of a series of racemic propargylic alcohols to corresponding (R)-enantiomers. The application also discloses the enantio-selective esterification of a propargylic alcohol from its racemate to prepare an (R)-ester. Enantioselectivity is enhanced by the use of experimentally determined enzymes. The propargylic alcohols and chiral esters may be useful in preparing compounds such as, for example, thrombin receptor antagonists.

  • Patent number: 5137743
    Abstract: Texturized oils and oil-continuous emulsions are prepared by combining liquid oils with edible polyester polymers. The resulting texturized oils and emulsions are gelled substances having a fat-like consistency which approximates the viscoelastic properties of solid fats, such as butter, margarine or hydrogenated vegetable oils, but contain no saturated fats. These texturized oils and emulsions can be used as a substitute for solid fats in food products and to make high-quality spreads containing reduced amounts of saturated fat.
