Enantiomeric Mixtures in Natural Product Chemistry: Separation and Absolute Configuration Assignment
Publikováno v:
Molecules, Vol 23, Iss 2, p 492 (2018)
Chiral natural product molecules are generally assumed to be biosynthesized in an enantiomerically pure or enriched fashion. Nevertheless, a significant amount of racemates or enantiomerically enriched mixtures has been reported from natural sources.

Vibrational circular dichroism (VCD) is one of the most powerful techniques to assess stereochemistry of chiral molecules in solution state. The need for quantum chemical calculations to interpret experimental data, however, has precluded its widespr

Twigs of Nectandra barbellata were extracted using a solution of the ionic liquid 1-butyl-3-methylimidazolium bromide (BMImBr) in H2O, assisted by microwave (MAE). After successive chromatographic steps, one sesquiterpene, costic acid, and three new
