Unprecedented Cu(I)-catalyzed microwave-assisted three-component coupling of a ketone, an alkyne, and a primary amine.
An efficient, microwave-assisted Cu(I)-catalyzed one-pot coupling of a ketone, an alkyne, and a primary amine (KA(2) coupling) is described, giving access to secondary propargylamines.
