Abstract: Enantiospecific synthesis reactions are of intense interest, owing to the increasing request for enantiopure compounds in both research and industry. Lithium amides containing a secondary chelating group are a class of powerful ligands for asymmetric addition reactions. Based on earlier experiences with lithium N,O and N,S amides, synthesis and properties of chiral lithium N,P amides and their use in asymmetric addition are investigated in the present thesis. Several chiral amines were s... more
