Optically active acyclic N-allylamino compounds with defined configurated trisubstituteddoublebonds were generated via a three step sequence. The first crucial step was a two-carbon chain elongation of chiral α-aminoacid esters succeeding in a Claisen ester condensation with acetic acid ester enolates. The so formed β-ketoesters were subjected to a one pot procedure of an enol trifluoromethanesulfonate
