CATALYTIC ASYMMETRIC DESYMMETRISATION OF PROCHIRAL AND MESOCYCLIC ANHYDRIDES |
| abstract |
One aspect of the present invention relates to cinchona-alkaloid-based catalysts. A second aspect of the invention relates to a method of preparing a derivatized cinchona-alkaloid catalyst. Another aspect of the present invention relates to a method of preparing a chiral, nonracemic compound from a prochiral cyclic anhydride or a meso cyclic anhydride, comprising the step of: reacting a prochiral cyclic anhydride or a meso cyclic anhydride with a nucleophile in the presence of a derivatized cinchona-alkaloid catalyst. Yet another aspect of the present invention relates to a method of kinetic resolution, comprising the step of: reacting a racemic cyclic anhydride with an alcohol in the presence of a derivatized cinchona-alkaloid catalyst. |
