Synthesis of tertiary propargylamines via a rationally designed multicomponent reaction of primary amines, formaldehyde, arylboronic acids and alkynes.

A novel approach for the synthesis of tertiary propargylamines is achieved through a Cu(OAc)2-catalyzed multicomponent reaction of primary amines, formaldehyde, arylboronic acids and alkynes, where a combination of PBM and A(3)-coupling reactions is involved in this new multicomponent reaction.
