2-Methylisocitrate (=3-hydroxybutane-1,2,3-tricarboxylic acid) is an intermediate in the oxidation of propanoate to pyruvate (=2-oxopropanoate) via the methylcitrate cycle in both bacteria and fungi (Scheme 1). Stereocontrolled syntheses of (2R,3S)- and (2S,3R)-2-methylisocitrate (98% e.e.) were achieved starting from (R)- and (S)-lactic acid (=(2R)- and (2S)-2-hydroxypropanoic acid), respectively
