Abstract A series of dimethyl (phenyl(phenylamino)methyl)phosphonates and novel dimethyl ((phenylamino)(2-(prop-2-yn-1-yloxy)phenyl)methyl)phosphonates as potential antifungal agents were synthesized via one-pot, three-component condensation of aldehydes, amines and trimethyl phosphite in solvent-freeconditions using [Et3NH][HSO4] as an efficient, eco-friendly and reusable catalyst. Compared to other

from aldehydes and amines) to yield the corresponding coupling products in good yield. The organocatalyst is air-stable, cost-effective, easy to handle, and easily removed from the reaction mixtures. α-Aminophosphonate derivatives were synthesized in excellent yield using PFPAT as an efficientorganocatalyst.

An atom-efficient, one-pot, three-component synthetic methodology has been developed for the preparation of α-aminophosphonates using the crystalline CuO- nanopowder as catalyst in solvent-free and ambient conditions, for the first time. The reaction involves the use of carbonyl compounds, amines and trimethyl phosphite. A wide range of substrates is compatible in this reaction, producing excellent
