Nucleophilic addition of dialkylphosphites to N-tert-butanesufinimines proceeds smoothly at room temperature in the presence of potassium carbonate or potassium fluoride, affording acyclic α-alkyl-α-aminophosphonates and a series of cyclic α-aminophosphonates in good chemical yields and modest to high diastereoselectivities.
