Montecrinanes A-C: Triterpenes with an Unprecedented Rearranged Tetracyclic Skeleton from Celastrus vulcanicola. Insights into Triterpenoid Biosynthesis Based on DFT Calculations

Three new triterpenoids with an unprecedented 6/6/6/6‐fused tetracyclic carbon skeleton, montecrinanes A–C (1–3), were isolated from the root bark of Celastrus vulcanicola, along with known D:B‐friedobaccharanes (4–6), and lupane‐type triterpenes (7–12). The stereostructures of the new metabolites w...
