O-Benzoylquinidine is an effective organocatalyst for the asymmetric chlorination of 3-aryloxindoles by using easily available N-chlorosuccinimide (NCS) as chlorine source to give the corresponding 3-aryl-3-chlorooxindoles in excellent yields and up to 93 % enantiomeric excess.
O-苯甲酰基奎尼丁是一种有效的有机催化剂,用于 3-芳基羟吲哚不对称氯化,通过使用容易获得的 N-氯代琥珀酰亚胺 (NCS) 作为氯源,以优异的收率和高达 93% 的对映体过量得到相应的 3-芳基-3-氯代吲哚。
