Novel Catalytic Process for Synthesis of Enantiomerically Pure Heterocyclic Compounds
- Technology Application
- The resulting products of this process are ideally suited for the manufacture of fine chemicals, agrochemicals, and pharmaceuticals. The products also provide an ideal platform for the development of libraries of highly functionalized, stereochemically-defined molecules suitable for lead identification and optimization in a medicinal chemistry setting.
- Detailed Technology Description
- Researchers at the University of California, Santa Barbara have developed new catalytic processes for the synthesis of enantiomerically pure heterocyclic compounds. These novel reactions convert simple, widely available starting materials into enantiopure heterocycles under mild conditions and without reagents, metals, or reaction byproducts. The novel catalysts used in these reactions are organic molecules that catalyze a variety of carbon-carbon, carbon-oxygen, and carbon-nitrogen bond forming reactions. For example, chiral lactam and lactone products are obtained in good yield and with >200:1 enantiomeric ratio. Both enantiomers of the chiral catalyst are available.
