| Outline of Final Research Achievements |
We have interested in the development of the conceptually new approach for the kinetic resolution of amines. Especially reactions based on asymmetric counteranion-directed catalysis with chiral Brønsted acid are very attractive. We hypothesized that the chiral ion pairs derived from a chiral phosphate anion and achiral acylpyridinium salts should be good reactive species in enantioselective acylation of amines. We screened pyridine derivatives, solvents, and amount of reagents. As a result of this screening, the reaction system gave the product in 20% conversion with 82 : 18 er (s = 5.3).
