1-Arylmethyl-2-(bromomethyl)aziridines were transformed into novel 2-(2-cyanoethyl)aziridines upon treatment with α-lithiated trimethylsilylacetonitrile in THF in an efficient and straightforward approach. The latter aziridines underwent ring opening by reaction with benzyl bromide in acetonitrile, affording 5-amino-4-bromopentanenitriles through a regiospecific ring opening of intermediate aziridinium

2-(2-Cyano-2-phenylethyl)aziridines were converted into novel trans-2-aminomethyl-1-phenylcyclopropanecarboxamides via regiospecific ring opening and 3-exo-tet cyclisation, thus providing the first convenient entry into the trans-isomer of Milnacipran as a useful template for further derivatisation. Furthermore, unprecedented 2-aminomethyl-1-benzylcyclopropanecarboxamides have been synthesized using
