  • Patent number: 7214819
    Abstract: A method of obtaining an enantioenriched organic compound comprising the steps of: 1) generating from a starting racemic, non-enantiopure or achiral compound a first mixture comprising at least one fluorous-tagged compound and at least one other non-fluorous tagged compound, at least one of these two compounds being enantioenriched relative to the starting compound; 2) contacting a first non-fluorous phase including the first mixture with a fluorous phase at a first phase interface, the fluorous-tagged compound distributing between the first non-fluorous phase and the fluorous phase; and 3) contacting the fluorous phase with a second non-fluorous phase at a second phase interface. The method further includes the step of having a third compound in the second non-fluorous phase that reacts with the fluorous-tagged compound to produce a second compound and the step of generating the first mixture by chemical or enzymatic kinetic resolution of a racemic or non-enantiopure compound.

  • Publication number: 20060128957
    Abstract: The present invention includes methods and compositions for increasing the fluorous nature of an organic compound by reacting it with at least one fluorous compound to produce a fluorous tagged organic compound. The increased fluorous nature of the fluorous tagged organic compound can then be utilized to separate the fluorous organic compound from untagged reagents, reactants, catalysts and/or products derived therefrom. The resultant fluorous tagged organic compound can be subjected to subsequent chemical transformations, wherein the fluorous nature of the tagged compound is utilized to increase the ease of separation of the fluorous tagged organic compound from untagged reagents, reactants, catalysts and/or products derived therefrom, after each chemical transformation.
