Abstract: Abstract A heterogeneous gold(I)-catalyzed cascade annulation reaction of aldehydes with propargylamine was achieved in 1,2-dichloroethane at 40 °C by using an MCM-41-immobilized phosphine gold(I) complex[MCM-41-PPh 3 -AuNTf 2 ] as catalyst, yielding a variety of 3-substituted… read more here.
