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

The preparation of substituted propargylamines via three-component reaction between aldehydes, terminal alkynes, and secondary amines following an environmentally acceptable methodology has been developed. The process has been carried out under solvent-free conditions in the presence of AgY zeolite. The catalyst can be easily recovered and reused for at least four cycles without significant decreases in yield and selectivity.
