New massarilactones C ( 3 ) and D ( 4 ), massarigenin E ( 5 ), and coniothyrenol ( 6 ) were isolated from Coniothyrium sp. together with the known graphislactone A ( 1 ) and massarilactone A ( 2 ). The relative configuration of coniothyrenol ( 6 ) with an unprecedented benzo[ a ]xanthene skeleton and ten chirality centers was determined by 1D‐ and 2D‐NMR spectroscopy.(© Wiley‐VCH Verlag GmbH & Co.
