CuCl-catalyzed cycloaddition of 1,3-butadiynes with primary amines: An atom-economic process for synthesis of 1,2,5-trisubsituted pyrroles

Zheng, Qingwei,Hua, Ruimao

, p. 4512 - 4514 (2010)

1,3-Butadiynes underwent inter- and intramolecular double hydroamination with primary amines in the presence of CuCl at 100°C to afford 1,2,5-trisubsituted pyrroles in good to high yields.
