AI Article Synopsis
- Three new compounds called Schicagenins A-C were found in the leaves and stems of the plant Schisandra chinensis.
- Their unique chemical structures include a specific tetracyclic oxa-cage motif and a side chain at C(9).
- The researchers used various spectroscopic methods and techniques like X-ray diffraction to analyze the structure and determine their absolute stereochemistry, while also proposing a possible way these compounds were biosynthesized.
Article Abstract
Schicagenins A-C (1-3), three unprecedented nortriterpenoids characterized with a tetracyclic oxa-cage motif and C(9) side chain, were discovered from the leaves and stems of Schisandra chinensis. Their structures were determined on the basis of extensive spectroscopic analysis, and the absolute stereochemistries were established by single-crystal X-ray diffraction and CD experiments. A plausible biosynthetic pathway of 1-3 was also discussed.
