参考标题:An Approach To Spirooxindoles Via Palladium-Catalyzed Remote C-H Activation And Dual Alkylation With Ch2Br2 作者:Changdong Shao,Zhuo Wu,Xiaoming Ji,Bo Zhou,Yanghui Zhang 摘要:A Facile And Efficient Approach For The Synthesis Of Spirooxindoles Has Been Developed Via The Coupling Of Spirocyclic C, C-Palladacycles With Ch2Br2. The Key Spirocyclic Palladacycles Are Generated Catalytically Via Intramolecular Remote C-H Activation. A Range Of Spirooxindoles Can Be Synthesized In Good To Excellent Yields From Readily Available Starting Materials.
