Enantiopure 4- and 5-Aminopiperidin-2-ones: Regiocontrolled Synthesis and Conformational Characterization as Bioactive β-Turn Mimetics

Starting from aspartic acid, we synthesized lactam-bridged β- and γ-amino acid equivalents. Using the 1,4-bis-electrophile 1b as a central intermediate, the 4- and 5-aminopiperidin-2-ones 4 and 8, respectively, were approached by regioselective functional

Homo-Freidinger lactams: Stereoselective synthesis of 4-aminopiperidin-2-one derivatives from aspartic acid

Starting from aspartic acid a stereoselective synthesis of enantiomerically pure 4-aminopiperidin-2-ones which can serve as conformationally restrained β-amino acid equivalents in peptidomimetics is described. The synthesis is based on the regioselective
