We report the first organocatalytic asymmetric synthesis of 3,3-disubstituted oxindoles featuring two heteroatoms at the C3 position. Importantly, 3-thiooxindoles and 3-alkoxyoxindoles are demonstrated to be reactive nucleophiles for the development of catalytic asymmetric reactions for the first time.
我们报道了首次使用有机催化方法进行的不对称合成3,3-二取代氧杂吲哚,该氧杂吲哚在C3位置具有两个杂原子。重要的是,首次证明了3-硫氧杂吲哚和3-烷氧氧杂吲哚可以作为反应性亲核试剂用于发展催化不对称反应。
