摘要
In the presence of catalytic amounts of Sc(DS)(3) and chiral bipyridine ligand 1, ring-opening desymmetrization of meso-epoxides with aromatic amines and indole derivatives proceeded smoothly in water without using any organic solvents to afford the corresponding adducts in high yields with high enatioselectivities. Interestingly, the Sc-caytalyzed reactions proceeded much faster in water than in dichloromethane.
