Two practical routes for the synthesis of benzhydrylamine derivatives in enantiomerically pure form have been developed. N-Acetylbenzhydrylamines can be synthesised in few steps and good yields starting from 1-aryl-1-propargylamines. The key steps are represented by the alkene-alkyne cross metathesis reaction and alkyne–diene methylene-free tandem-metathesis reaction; these reactions have been performed
