Chiral aminoalkyl epoxyaziridine 1 is synthesized in high yield and diastereoselectivity from l-serine. Ring opening of epoxyaziridine 1 with primary amines is carried out with total chemo- and regioselectivity, affording chiral polyfunctionalized piperidines 8. The structure of these trisubstituted piperidines is established by NMR studies.
