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. nucleophilic additions - thiophosphonates - imines - sulfinamides - sulfonamides
