Chiral phosphorousacid diamides were prepared by condensation of N,N′-disubstituted C2 diamines with PCl3 followed by an equivalent of water. Deprotonation of these acids with n-butyl lithium or LDA gave the lithium salt which reacted smoothly with alkyl halides to give the substituted phosphonamides in good yield.
