Zusammenfassung:
The development of amino acid esters as chiral auxiliary groups for the asymmetric construction of N-heterocycles by means of aza Diels-Alder reactions, Mannich reactions, Pictet-Spengler reactions and 1,3-dipolar cycloadditions is described. Also their application in the steric steering of carbo Diels-Alder reactions, radicalic transformations and enantioselective nucleophilic additions to carbonyl groups is highlighted.
