Rhodium-catalyzed reactions of arylbismuth and aryllead reagents with a chiral glyoxylate hydrate in air and water: water-promoted diastereoselectivity enhancement

In the presence of a rhodium catalyst, a chiral glyoxylate hydrate reacts with arylbismuth and aryllead reagents in water and under an atmosphere of air to give the corresponding addition products in high yields. The diastereoselectivities of the reactions were dramatically improved by using water a...

Description
Summary:In the presence of a rhodium catalyst, a chiral glyoxylate hydrate reacts with arylbismuth and aryllead reagents in water and under an atmosphere of air to give the corresponding addition products in high yields. The diastereoselectivities of the reactions were dramatically improved by using water as the solvent. Graphic
