ORGN 22 |
| Asymmetric Michael reactions catalyzed by a chiral bicyclic guanidine are described. A variety of 1,3-dicarbonyl compounds, including S,S'-dialkyl dithiomalonates, dialkyl malonates, 1,3-diketones and benzoylacetate, can function as the Michael donors in the reaction with various N-alkyl maleimides and 2-cyclopenten-1-one, giving high enantioselectivities and yields. |
