Untersuchungen zur Charakterisierung des Prochamazulens Matrizin aus Matricaria chamomilla L. / Studies on the Characterization of the Chamazulene Precursor Matricine from Matricaria chamomilla L.

Abstract
The relative configuration of the thermolabile chamazulene precursor matricine was established by NMR spectrometric studies. The NMR spectral data are consistent with the well-known structure of the chamomile component. The levorotatory natural substance can be specified stereochemically as (-)-(3S, 3aR, 4S, 9R, 9aS, 9bS)-4-acetoxy-2,3,3a,4,5,9,9a,9b-octahydro-9-hydroxy-3,6,9-trimethylazuleno[4,5-b]furan-2-one.
