Technical Notes:
1.Conjugate Addition: Primary amine -thiourea derivative is an active and highly enantioselective catalyst for the conjugate addition of ketones to nitroalkenes.
2.Michael Addition: The asymmetric Michael addition of dioxindoles to ß-substituted nitroalkenes is reported. The bifunctional primary amine-thiourea, by means of a non-covalent-based mode of catalysis, secures
direct access to 3-substituted 3-hydroxyoxindole derivatives with high stereocontrol.
