A highly efficient microwave-assisted three-component reaction between an aldehyde, a primary amine and an alkyne was developed using an inexpensive Cu(i)/Cu(ii) catalytic system and water as solvent.

gold(I) catalysis generally resulted in a formation of oxazolidin‐2‐imines as major products while the application of silver(I) triflate selectively provided the corresponding imidazolidin‐2‐ones. An attempt to rationalize the observed chemoselectivity is described. The scope of both processes was demonstrated through the use of variously substituted secondary propargylic amines.
