  • 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.
