Abstract

Abstract All of the three possible stereoisomers of (5S, 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 ...
