  • Patent number: 7423154
    Abstract: An asymmetric synthesis of diarylmethylpiperazines is described. The synthetic route enables preparation of a variety of enatiomerically pure amines with different N-alkyl groups. The invention includes an asymmetric addition of organometallic compounds to chiral sulfinimine to give adducts in predominantly one diastereomer can subsequently be transferred into pure enantiomers of by cleavage of the chiral auxilliary which is followed by synthesis of the piperazine ring by alkylation procedures.
