A transition metal‐free approach for the N‐arylation of amino acid derivatives has been developed. Key to this method is the use of unsymmetric diaryliodonium salts with anisyl ligands, which proved important to obtain high chemoselectivity and yields. The scope includes the transfer of both electron deficient, electron rich and sterically hindered aryl groups with a variety of different functional
已经开发出一种用于氨基酸衍生物N芳基化的无过渡金属方法。该方法的关键是使用带有茴香基配体的不对称二芳基碘盐,这被证明对于获得高化学选择性和产率非常重要。范围包括缺电子、富电子和空间位阻芳基与各种不同官能团的转移。此外,环状二芳基碘鎓盐成功地用于芳基化。获得保留对映体过量的N-芳基化产物。
