- Abstract
- The absolute configuration of rhizopine, an opine-like natural product present in nitrogen-fixing nodules of alfalfa infected by rhizobia, is elucidated using a combination of state-of-the-art analytical and semi-preparative supercritical fluid chromatography and vibrational circular dichroism spectroscopy. A synthetic peracetylated racemate was fractionated into its enantiomers and subjected to absolute configuration analysis revealing that natural rhizopine exists as a single enantiomer. The stereochemistry of non-derivatized natural rhizopine corresponds to (1R,2S,3R,4R,5S,6R)-4-amino-6-methoxycyclohexane-1,2,3,5-tetraol.
