英文摘要：

Objective To synthesis 3 - halooxindoles and use them to construct 3,3 - disubstituted oxindoles. Methods The 3,3 - disubstituted oxindoles were synthesized by using β - ketoacids, oximes and sodium p - tolu- enesulfinate as nucleophiles, respectively, reacting with 3 - halooxindoles combining with base as catalysts. Results A class of 3 -halooxindoles and a series of 3,3 -disubstituted oxindoles bearing a carbon, an oxygen or a sulfur atom at the C3 - position were synthesized. Conclusion This procedure has some advantages, such as readily available starting materials, mild reacition conditions and easy manipulation, as well as provides an effi- cient method for the construction of 3,3 -disubstituted oxindoles.
