Abstract

Abstract: Three new xanthone dimers, named phomoxanthones C–E (1 –3 ), were obtained from the Thai mangrove fungus Phomopsis sp. xy21, together with four known ones. The structures of these compounds were elucidated by the analysis of HRESIMS and extensive NMR spectroscopic data. The absolute configuration of1 was established by the analysis of single-crystal X-ray diffraction with Cu Kα radiation. Phomoxanthones C (1 ) and D (2 ) possess a highly oxidized hexahydroxanthone skeleton. Abstract :
