Outline of Final Research Achievements |
UV-Vis absorption spectrum and ESI-MS analysis revealed that diastereoselectivity of the rare earth metal triflate-catalyzed secondary benzylation of ketoester was controlled by the steric effect of 1:1:1 complex of the ketoester enol form, the ketoester keto form, and the lutetium ion. Optically active rare earth metal Lewis acids and chiral thiourea catalysts were examined for the enantioselective reaction of the cationic species. Chiral thiourea-catalyzed reaction of the allylic alcohol and the sulfonamide gave quinoline derivative enantioselectively via a kinetic resolution of the quinoline product.
