Description SbCl3 adsorbed on Al2O3 is found to be an efficient and recyclable catalyst in promoting three-component coupling reactions of aldehydes (aromatic and aliphatic), amines (aryl amines, aliphatic amines and esters of S-a-amino acids) and dialkylphosphites to afford the corresponding a-aminophosphonates in high yields. The ethyl ester of S-phenylalanine was observed to yield the corresponding
a-aminophosphonate with S,S-diastereoisomer formed in dominance over the S,R-diastereoisomer.
