A Versatile and Highly StereoselectiveSynthesis of Diethyl (1-Aminoalkyl)thiophosphonates

A series of chiral diethyl (1-aminoalkyl)thiophosphonates was synthesized in high yield and excellent enantioselectivity by nucleophilic addition of diethyl thiophosphonate to N-(tert-butylsulfinyl)imines under mild conditions. There is no evidence indicating that the reaction is influenced by electronic or steric effects of the substrates.
