  Stereoselective Synthesis of Multisubstituted Butadienes through Directed Mizoroki−Heck Reaction and Homocoupling Reaction of Vinyl(2-pyridyl)silane

  摘要：

  We have developed the homocoupling reaction of alkenyl(2-pyridyl)silanes mediated by Cul and CsF, in which the strong directing effect of the 2-pyridyl group was observed. The homocoupling reaction was successfully integrated with the Mizoroki-Heck reaction of vinyl(2-pyridyl)silane with aryl halides, enabling a rapid and stereoselective synthesis of multisubstituted butadienes. From a relatively small compound library, it was possible to detect a number of fluorescent butadienes with a wide range of fluorescence color variations (blue to reddish-orange).
