Blum-Ittah aziridine synthesis

Ring opening of oxiranes using azide followed by PPI13 reduction of the intermediate azido alcohol to give the corresponding aziridines. Cf. Staudinger reduction. 

Regardless of the regioselectivity of the Sn2 reaction of the azide, the ultimate stereochemieal outcome for the aziridine is the same.
