  摘要：

  This Letter described a facile approach to synthesize (E)-2-alkenylquinoline derivatives via C(sp(3))-H functionalization of 2-methylquinolines under catalyst-free conditions. A variety of electronically and sterically diverse 2-methyl quinoline and aromatic aldehydes were well tolerated. (C) 2014 Elsevier Ltd. All rights reserved.

• Iodine-Catalyzed Direct C–H Alkenylation of Azaheterocycle N-Oxides with Alkenes

  azaheterocycle N-oxides with alkenes catalyzed by iodine under metal- and external oxidant-free reaction conditions has been developed. A variety of (E)-2-styrylazaheterocycles have been produced in moderate to excellent yields. The mechanistic exploration indicated that the N-oxide group played dual roles as both the directing group and an internal oxidant in this catalytic cycle.
