Monochiral N-Diphenyphosphinyl aziridines () may efficiently be prepared from monochiral 2-aminoalcohols. Such aziridines undergo ring-opening reaction with a variety of nucleophiles in good yield. Dephosphinylation is accomplished under mild conditions.

N,O-bis(diphenylphosphinyl)-2-(hydroxymethyl)aziridine (‘DiDpp’, 1) is efficiently prepared from 2-aminoethane-1,3-diol: this activated aziridine undergoes two sequential reactions with copper(I)-modified Grignard reagents, yielding α-branched N-Dpp amines in good yield.
