Transition Metal-Catalyzed Synthesis of Pyrroles from Dienyl Azides
摘要:
A range of 2,5-disubstituted and 2,4,5-trisubstituted pyrroles can be synthesized from dienyl azides at room temperature using catalytic amounts of Znl(2) or Rh-2(O2CC3F7)(4).

Pyrrole is a unique aromatic molecule as it can readily undergo substitution at all five positions but obtaining the desired regioisomer can prove difficult to control. We now report our results on the regioselective arylation of pyrrole, utilizing selective halogenation and the Suzuki-Miyaura reaction to prepare C4-, C5- and C3-aryl derivatives. We have applied this methodology to the synthesis of
