title: Fomlactones A-C, novel triterpene sactones from Fomes cajanderi.
abstract: Investigation of the neutral ether extracts of the fungus Fomes cajanderi led to the isolation of three novel ketal lactones named fomlactones A (1), B (2), and C (3). These compounds were identified by analysis of IR, HRMS, CD, and 1D and 2D NMR data. The structure of fomlactone C (3) was confirmed by X-ray diffraction analysis.
