unprecedented method for the construction of optically active 3,3′-disubstituted oxindoles via an organocatalyzed decarboxylative stereoablation reaction has been developed. We describe the first asymmetric reaction between β-ketoacids and 3-halooxindoles utilizing an organocatalyst. This method allows for the formation of a variety of 3,3′-disubstituted oxindoles bearing a keto-carbonyl group, which
已经开发了通过有机催化的脱羧立体消融反应构造旋光的3,3′-二取代的羟吲哚的空前方法。我们描述了利用有机催化剂的β-酮酸和3-卤代肟之间的第一个不对称反应。该方法允许以中等至良好的产率和高对映选择性形成带有酮-羰基的各种3,3'-二取代的羟吲哚,使用其他方法不易获得。
