Cinchona Alkaloids in Synthesis and Catalysis: Ligands, Immobilization and Organocatalysis
Choong Eui Song
John Wiley & Sons, Sep 3, 2009 - Science - 512 pages
This comprehensive review of cinchona-based chiralilty inducers and their applications covers every topic, including ligands, immobilization and organocatalysis. Each chapter summarizes the scope and limitations of the new methods and technologies, while the final chapter contains carefully selected working procedures of cinchona alkaloid-promoted reactions organized according to reaction type.
Invaluable reading for anyone wanting to learn about the current state of this hot topic.
