摘要：

(Chemical Equation Presented) C-C bonds from C-H bonds: Tethering nucleophilic groups to benzylic and allylic ethers allows cyclization reactions by DDQ-mediated oxidative carbon-hydrogen bond activation (see scheme; DDQ = 2,3-dichloro-5,6-dicyano-1,4-benzoquinone). The method is operationally simple, proceeds with a wide range of ether groups, is tolerant of functional groups, and is highly stereoselective. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
