The first report on the use of N-sulfinyl benzylcarbamate for the preparation of N-Cbz sulfilimine from the corresponding sulfoxide is reported. The sulfilimine moiety is utilized as an intramolecular nucleophile for the regio- and stereoselective heterofunctionalization of an alkene to furnish a bromo carbamate which is used as a key advanced intermediate in the synthesis of representative α-hydroxy-β-amino
首次报道了使用N-亚磺酰基苄基氨基甲酸酯从相应的亚砜制备N- Cbz亚硫亚胺的报道。硫亚胺部分被用作分子内亲核试剂,用于烯烃的区域和立体选择性杂官能化,以提供溴代氨基甲酸酯,该氨基甲酸酯用作代表性的α-羟基-β-氨基酸衍生物的合成中的关键高级中间体。
