Stereohemistry of reaction of a phosphonamidic chloride with t-butylamine
Abstract
Both diastereoisomer of ButP(O)(Cl)NHR [RNH =(S)-PhMeCHNH] give the same mixture (55/45) of the diastereoisomers of ButP(O)(NNBut)NHR on reaction with ButNH2 in dilute MeCN solution, but some stereospecificity is seen at higher amine concentrations.
