    Description / Table of Contents: Synthese eines desoxanalogen von (3S)-Citryl-CoA: (3RS)-3,4-Dicarboxy-3-hydroxybutyl-CoADer Citrylthioester 1 wurde im mmol-Maßstab mit Natriumtetrahydroborat in 70proz. Ausbeute zu 2-Hydroxy-2-(2-hydroxyethyl)butandisäure (2) reduziert. Die Säure wurde in den Dimethylester 3 und weiter in das 2-(2-Bromethyl)-Derivat 4 umgewandelt. Dessen Reaktion mit Coenzym A lieferte die Titelverbindung 7, entweder im Eintopfverfahren oder durch Hydrolyse des isolierten Dimethylesters 6. Die mit 7 und dem Enzym Citratsynthase des Tricarbonsäurezyklus erzielten kinetischen und röntgenstrukturanalytischen Ergebnisse werden diskutiert.
    Notes: The citryl thioester 1 was reduced in mmol scale with sodium tetrahydroborate to yield 2-hydroxy-2-(2-hydroxyethyl)butanedioic acid (2) in 70% yield. The acid was converted into the dimethyl ester 3 and further to the 2-(2-bromoethyl) derivative 4. This bromide was used to prepare the title compound 7 by reaction with coenzyme A, either directly, or by hydrolysis of the isolated dimethyl ester 6. The kinetic and X-ray crystallographic results obtained with 7 and the enzyme citrate synthase of the tricarboxylic acid cycle are discussed.
