Herein, we report a C3 and C1 coupling approach between vinyl 1,3-dithiane derivatives and alkynylsilanes for the construction of highly substituted conjugated dienes. Through the regioselective dual 1,3-sulfur migration process, this method enabled the synthesis of a wide range of highly substituted (E)-1,3-dienes stereoselectively in moderate to high yields, which provided one alternative way to synthesize
在此,我们报道了乙烯基1,3-二噻烷衍生物和炔基硅烷之间的C 3和C 1偶联方法,用于构建高度取代的共轭二烯。通过区域选择性双1,3-硫迁移过程,该方法能够以中等到高产率立体选择性合成多种高度取代的( E )-1,3-二烯,为合成相应的共轭化合物提供了一种替代方法。二烯酮。
