Iron(II) efficiency: The iron complexes of N4 ligands, derived from proline and benzimidazole, exhibited an unprecedented activity and enantioselectivity for the epoxidation of a variety of di‐ and trisubstituted enones (see scheme). This system, based on synthetic non‐heme iron catalysts, provides ready access to a wide range of epoxyketones of high enantiomeric purity.
铁(II)的效率:源自脯氨酸和苯并咪唑的N 4配体的铁配合物对各种二和三取代的烯酮的环氧化反应显示出空前的活性和对映选择性(参见方案)。该系统基于合成的非血红素铁催化剂,可以轻松获得各种高对映体纯度的环氧酮。
