Synthesis of enantiopure allylamines by reductive alkylation of amino epoxides with organolithium reagents.

[reaction: see text] Transformation of enantiopure (2R,1'S)-2-(1-aminoalkyl)epoxides 1 into the corresponding allylamines 2 is described. The opening of the epoxide ring with different organolithium compounds takes place with total selectivity and in high yields.
