cross‐coupling of internal alkenes of α‐oxoketene dithioacetals with terminal alkenes has been successfully realized by palladium‐catalyzed CH bond activation, affording functionalized 1,3‐butadienes. Condensation of the resultant 1,3‐butadienes by diamines efficiently produced potentially bioactive bicyclic pyridone derivatives (see scheme).
甲高度选择性直接交叉偶联与末端烯烃α-oxoketene二硫的内部烯烃的已通过钯催化的C ^成功地实现 H键活化,得到官能化的1,3-丁二烯。二胺将所得的1,3-丁二烯缩合可有效产生具有潜在生物活性的双环吡啶酮衍生物(请参见方案)。
