The scope of the NCS-mediated amination/[2,3]-sigmatropic rearrangement of enantioenriched allylic selenides has been expanded to provide access to three new product classes. The use of N-protected amino acid amides provides a novel strategy for accessing peptide chains containing unnatural vinyl glycine amino acid residues. Also reported is the use of amino acid esters, allowing the diastereoselective
NCS介导的对映体富集的烯丙基硒化物的胺化/ [2,3]-σ重排的范围已得到扩展,可以提供三种新产品类别。使用ñ -保护的氨基酸酰胺提供用于访问含有非天然乙烯基甘氨酸氨基酸残基的肽链的新策略。还报道了使用氨基酸酯,其允许非对映选择性地合成N,N-二羧甲基胺,这是许多药物中发现的基序。此外,使用多种N-芳族和N-杂芳族胺可形成对映体富集的N-芳基氨基酸,一种在许多合成和生物学上令人感兴趣的化合物中发现的基序。
