Outline of Final Research Achievements |
Oxidative kinetic resolution of racemic secondary alcohols is useful for obtaining optically active alcohols. In this study, asymmetric aerobic alcohol oxidation using chiral nitroxyl radical/copper cooperative catalysis has been investigated. Novel chiral nitroxyl radicals were synthesized and several racemic secondary alcohols were found to be kinetically resolved with moderate selectivity under aerobic oxidation conditions catalyzed by the novel chiral nitroxyl radicals and copper salts.
