amine and phosphite compounds to form corresponding α-aminophosphonates in a one-pot, three-component reaction. Selected α-aminophosphonates were entered into a biological assay test and were studied by docking methods, using Autodock 3.0. The results showed that the reactions were carried out mildly and eco-friendly to form α-aminophosphonates in high yields. Some were found to have cytotoxic activity
