    Description / Table of Contents: Enantiomerically Pure Building Blocks for Syntheses from Branched MalatesIsocitric acid lactone (13) and the chiral building blocks (2S,3R)-4-bromo-1,2-epoxy-3-methylbutane (21), cis- and trans-2,3-epoxy-2-methylsuccinates (23, 24), and the singly protected (2R)-2-methyl-, -2-allyl- and -2-benzyl-1,3-propanediols (32a, b, c) are readily accessible in diastereomerically and enantiomerically pure forms from malates (8, 16, 25a, b, c) which are alkylated in position 3.
    Notes: Ausgehend von in 3-Stellung alkylierten, enantiomerenreinen Äpfelsäureestern (8, 16, 25a-c) wurden (+)-Isocitronensäurelacton (13) sowie die Synthesebausteine (2S,3R)-4-Brom-1,2-epoxy-3-methylbutan (21), cis- und trans-2,3-Epoxy-2-methylbernsteinsäureester (23, 24) und die einfach geschützten (2R)-2-Methyl-, -2-Allyl- und -2-Benzyl-1,3-propandiole (32a, b, c) diastereomeren- und enantiomerenrein hergestellt.
