Abstract

The organic extract of Xenia faraunensis was found to contain besides xeniolide A and B three novel diterpenes: xeniafaraunol A (1), -B (2) and faraunatin (3). The structure of compounds 1-3 was defined by spectral methods and mainly 1D and 2D NMR experiments. Xeniafaraunol A and B (1 and 2) are of a novel bicyclo[7.4.0] tridecane carbon skeleton and faraunatin (3) is an unprecedented prenylated bicyclogermacrene. Compounds 1-3 are cytotoxic against P388 cells.
