An efficient method for the preparation of 3-sulfonylated 3,3-disubstituted oxindole derivatives has been developed. The protocol involves a base-catalyzed addition of sulfinate salts to 3-halooxindoles, affording a wide range of 3-sulfonylated 3,3-disubstituted oxindoles in good to excellent yields under mild conditions. A preliminary trial of asymmetric catalytic version was conducted and gave promising
已经开发了制备3-磺酰化的3,3-二取代的羟吲哚衍生物的有效方法。该方案包括在3-卤代硫醇中催化亚磺酸盐的碱催化加成反应,在温和条件下以良好或优异的收率提供了多种3-磺酰化的3,3-二取代的羟吲哚。进行了不对称催化形式的初步试验,并给出了有希望的对映选择性。在质谱分析的帮助下,初步探索了该反应的机理。
