Asymmetric α-oxyamination of aldehydes by synergistic catalysis of imidazolethiones and metal salts†
Abstract
Novel and efficient imidazolethione catalysts combined with metal salts were successfully introduced to the asymmetric α-oxyamination of aldehydes. The desired products with high yields and good to excellent enantioselectivities were obtained via a one-pot oxidation–oxyamination reaction system.
