Samariumdiiodide is an efficient catalyst for the aza-Michael addition of O-benzylhydroxylamine to α,β-unsaturated N-acyloxazolidinones leading to mixtures of the Michael adduct and the product resulting from its amidation. Samarium iodobinaphtholate catalyzed reactions selectively afford the Michael adducts with enantiomeric excesses up to 88 %. An isoinversion effect with temperature is observed
二碘化钐是一种有效的催化剂,用于将 O-苄基羟胺与 α,β-不饱和 N-酰基恶唑烷酮进行氮杂-迈克尔加成,从而形成迈克尔加合物及其酰胺化产物的混合物。碘联萘酸钐催化的反应选择性地提供对映体过量高达 88% 的迈克尔加合物。在 -40 °C 时观察到对映体过量最高的温度的同位倒置效应。
