experimental part, p. 3242 - 3246 (2009/06/25)
A series of saccharide-derived bifunctional tertiary amine-thioureas for the asymmetric Michael addition reaction have been designed and synthesized. The addition products between malonates and various nitroolefins were obtained in high yields (up to 99%)

A bifunctional chiral thiourea organocatalyst bearing a glycosyl scaffold and a tertiary amino group proved to be an effective organocatalyst for the asymmetric Michael addition of acetylacetone to nitroolefins. The corresponding adducts were obtained in
