An efficient and facile method has been developed for the synthesis of quaternary carbon propargylamines via a one-pot tandem reaction of amines, alkynes, and alkynes under neat condition. Both aliphatic and aromatic terminal alkynes are well compatible with the established reaction, with respect to aliphatic alkynes, AgOTf was used as catalyst for the Markovnikov amine-alkyne-alkyne coupling process. When aromatic alkynes were used as substrates, the reaction was promoted by CuBr2/Zn (OTf)2 co-catalytic system. This tandem reaction exhibits excellent atom efficiency and provides an attractive approach to a diverse range of quaternary carbon propargylamines.

Key words: propargylamines, quaternary carbon, alkynes, neat condition, green organic synthesis
