A sustainable magnetic core-shell nanocatalyst FeO@C@Fe(III) was successfully applied in the synthesis of a series of 2-nitro-2,3-unsaturated -glycosides with excellent yields (up to 89%) and high stereoselectivity (α:β > 19:1). The substrate ranges are widely applicable, including different kinds of alcohols and even structurally complex acceptors. In addition, phenols could be applied in good yields. Moreover, the catalyst could be easily separated from the reaction by the application of an external magnetic force and reused a minimum of five times without any significant decrease in catalytic performance.
一种可持续的磁性核壳纳米催化剂FeO@C@Fe(III)成功应用于一系列2-硝基-2,3-不饱和糖苷的合成，产率优异（高达89%）且立体选择性高（α:β>19:1）。底物范围广泛适用，包括不同种类的醇类甚至结构复杂的受体。此外，酚类也能以良好的产率应用。而且，通过施加外部磁力，该催化剂可轻松从反应中分离出来，并至少重复使用五次，催化性能无任何显著下降。
