AgY zeolite as catalyst for the effective three-component synthesis of propargylamines

Green synthesis of CuO nanoparticles by aqueous extract of Anthemis nobilis flowers and their catalytic activity for the A3 coupling reaction

“…Purification was performed by flash column chromatography. All compounds were known and were characterized by spectral analysis or melting points [17,[41][42][43][44][45][46][47][48][49][50][51][52][53][54]. (Table 2, …”

“…In the last decade many efforts have been done to develop new methodologies for the synthesis of propargylamines through one-pot three-component condensation reaction (A 3 ) of aldehydes, amines, and alkynes in the presence of homogeneous catalysts such as Zn salts, Cu salts, Fe salts, Ag salts, Au salts [4][5][6][7][8][9].…”

Silver and gold-catalyzed multicomponent reactions

“…As Li and Van der Eycken reported in their valuable reviews, some other silver salts (e.g., Ag 3 PW 12 O 40 [6] , AgX [7]), complexes [8], zeolites [9] and nanoparticles [10–11] have been explored to catalyze the A 3 -coupling, but only recently, silver–NHC complexes were found to be valuable catalysts for this MCR. Their first application was reported by Wang and co-workers in 2008 [12], who developed a polystyrene-supported NHC–Ag(I) complex as an efficient catalyst for the A 3 -coupling under solvent-free conditions, at room temperature, and under a nitrogen atmosphere.…”

Synthetic Chemistry with an Eye on Future Sustainability

“…Both aromatic and aliphatic aldehydes were able to undergo addition to afford the corresponding three-component propargylamines effectively. Subsequently, Maggi et al found that silver-nanoparticles and supported silver can also catalyze the A 3 reaction efficiently under various conditions [100]. Rueping et al reported the asymmetric silver-catalyzed alkyne iminium addition reaction [101].…”
