A highly efficient copper-catalyzed asymmetric insertion of α-diazoesters into N−H bonds has been realized by using chiral spiro bisoxazoline ligands, affording α-amino acid derivatives in high yields with excellent enantioselectivities.
通过使用手性螺双恶唑啉配体实现了在铜催化下高效地将 α-重氮酯不对称插入到 N-H 键中,从而以高产率提供具有优异对映选择性的 α-氨基酸衍生物。
