Although reactions of 2,3-trans-N-arylsulfonyl-3-alkyl-2-alkenylaziridines with organocopper reagents give a mixture of two or three products, the corresponding 2,3-cis-isomers provide a highly efficient route to synthetically important nonracemic (E)-allylamines. It is also found that the reaction proceeds via the well-known anti-S(N)2' pathway.
