All of the three possible stereoisomers of (5 S ,1′ S )‐4‐carboxy‐5‐methyl‐1‐(1′‐methylpropyl)heptanoic acid were synthesized and their stereostructures assigned unambiguously by 13 C‐NMR and X‐ray analyses. The melting points and the specific rotations of the three isomeres were quite different from those reported for Kögl's auxin‐glutaric acid and its two stereoisomers. This fact indicates the non‐existence of Kögl's auxin‐a and ‐b.
