Organoiodine-catalyzed enantioselective intramolecular oxyaminations were realized by the use of benzyl N-(fluorosulfonyl)carbamate as the exogenous nitrogen source. The method allows access to enantioenriched lactones and oxazolines, starting from γ,δ- and δ,ε-unsaturated esters and N-allyl amides, respectively.
通过使用苄基N-(氟磺酰基)氨基甲酸酯作为外源氮源,实现了有机碘催化的对映选择性分子内氧化。该方法允许分别从γ,δ-和δ,ε-不饱和酯和N-烯丙基酰胺开始获得对映体富集的内酯和恶唑啉。
