2‐Substitute an indole! The asymmetric organocatalytic conjugate addition of 1‐acetylindolin‐3‐one to enones has been developed. This organocatalytic approach constitutes an easy and efficient method for the direct preparation of 2‐substituted indolin‐3‐ones in high enantioselectivities (see scheme).

使用伯-仲二胺催化剂轻松制备2取代的Indolin-3

2-取代吲哚！已开发了将1-乙酰吲哚-3-酮与烯酮不对称的有机催化共轭加成物。这种有机催化方法构成了一种简单而有效的方法，用于以高对映选择性直接制备2-取代的吲哚-3-酮（参见方案）。
