The asymmetric Michael addition of cyclohexanone to nitroolefins was investigated using R-phenylglycine derivatives along with L-prolinamides as chiral catalysts. The desired products were obtained in excellent yields with enantioselectivities up to 90% ee and diastereomeric ratio up to 98:2 of the syn addition product.eninfo:eu-repo/semantics/openAccessAminesAsymmetric CatalysisMichael AdditionNitroolefinsOrganocatalysisArticle3656596702-s2.0-84870786682Q3WOS:000311947000003Q310.3906/kim-1110-25
