    Description / Table of Contents: Enantioselective Synthesis of (-)-(R)-and (+)-(S)-[6]-Gingerol-Pungent Principle of Ginger1)Enantioselective syntheses of the major pungent principle of ginger (+)-(S)-[6]-gingerol [(S)-1] and the (-)-(R)-antipode in good yields and optical yields of 33-39% are described. As a key step, and aldol reaction is used with the “anion” of the chiral hydrazone 6 and n-hexanal. The chiral auxiliary compound 13 is prepared in five steps from (R)-glutamic acid.
    Notes: Enantioselektive Synthesen des Hauptgewürzprinzips des Ingwers (+)-(S)-[6]-Gingerol[(s)-1] und des (-)-(R)-Antipoden werden in guten Ausbeuten und mit 33-39% optischer Ausbeute beschrieben. Als Schlüsselschritt wird eine Aldolreaktion mit dem″ Anion″ des chiralen Hydrazons 6 und n-Hexanal benutzt. Die chirale Hilfsverbindung ′13 wird in fünf Stufen aus (R)-Glutaminsäure hergestellt.
