A highly efficient intramolecular hydroamination reaction of
heterocycle-centered aminoalkynes using both substituted and free
amines catalyzed by PdCl2/FeCl3 catalytic
system to form the biologically important pyrrolocoumarin and pyrroloquinolone derivatives
is reported. The use of both aliphatic and aromatic substituted
alkynes with different heterocyclic skleton in this strategy demonstrated
the diversity of this method.
