摘要：

New types of Lewis acids based on group 3 and 4 elements (Sc, Y, La, Zr, and Hf) have unique properties compared to typical Lewis acids. This article describes our recent results on Lewis acid-catalyzed enantioselctive reactions using these elements and their unique properties. Asymmetric versions of Diels-Alder reactions, [2+2] cycloaddition, aza Diels-Alder reactions, 1,3-dipolar cycloaddition, and Mannich-type reactions using chiral rare earth and zirconium catalysts are discussed.
