    摘要: Nucleophilic oxygen species, such as primary alcohols, carboxylates, and water, are added to vinyl epoxides in a highly regioselective and enantioselective manner, providing a convenient route to enantiomerically enriched 2,2-diols and oxygen-containing heterocycles. The reaction employs a chireal Pd(0) complex and a borane or borate as co-catalysts. Also described are similar additions of nitrogen nucleophils, and the addition of carbonates to vinyl epoxides using a chiral Pd(0) catalyst.
