An assisted tandem catalytic transformation of diallyl amines and diallyl ethers into N-aryl pyrroles and furans, respectively, is described. The sequence relies on ring closing metathesis followed by dehydrogenation of the initially formed dihydropyrroles and dihydrofurans. Both steps are Ru-catalyzed, but the sequence requires only one precatalyst, because conversion of the metathesis catalyst into
描述了将二烯丙基胺和二烯丙基醚分别辅助催化串联转化为N-芳基吡咯和呋喃。该序列依赖于闭环易位,然后使最初形成的二氢吡咯和二氢呋喃脱氢。这两个步骤都是Ru催化的,但是该顺序仅需要一种预催化剂,因为易位催化剂转化为脱氢催化剂的过程是由氧化剂叔丁基过氧化氢引发的,它是就地实现的。
