N-(4-Toluenesulfonyloxy)carbamates based on a range of common amine protecting groups serve as preformed nitrogen sources in the intermolecular osmium-catalyzed oxyamination reaction of a variety of mono-, di-, and trisubstituted alkenes. The reactions occur with low catalyst loadings and good yields and afford high regioselectivity for unsymmetrically substituted alkenes.
在一系列单,二和三取代烯烃的分子间催化的氧化胺化反应中,基于一系列常见胺保护基的N-(4-甲苯磺酰氧基)氨基甲酸酯用作预制的氮源。该反应以低的催化剂负载量和良好的收率进行,并且对于不对称取代的烯烃提供高的区域选择性。
