摘要：

High yields and enantioselectivities are obtained in a dynamic kinetic asymmetric transformation in which the C-O bond of alcohols, silyl ethers, and acetals are substituted by a C-C bond. For example, the racemic indanyl silyl ether 1 is converted into (S)-2 in the presence of the chiral Lewis acidic TiIV complex 3.
