A highly enantioselective method for the catalytic opening of aromatic meso-epoxides with aniline derivatives was developed. The desired chiral β-amino alcohols were obtained in mostly good to very good yields with excellent enantioselectivities. Structural evidence of the pre-catalyst revealed a scarcely disclosed heptadentate Fe(II) complex with the chiral bipyridine ligand.
发展了一种高对映选择性的催化芳香内环氧开环方法,使用苯胺衍生物。所需的手性β-氨基醇以大多良好至非常好的收率和优异的对映选择性获得。前催化剂的结构证据揭示了一种几乎未被披露的七配位 Fe(II)配合物,具有手性联吡啶配体。
