Abstract:
Chemical investigation of a Great Barrier Reef ascidian, Aplidium longithorax has resulted in the isolation of two new para-substituted cyclofarnesylated hydroquinone compounds, longithorols C (1) and D (2), and a novel macrocyclic chromenol, longithorol E (3). Longithorol C (1) had its absolute stereochemistry determined by the advanced Mosher method and all compounds had their structures determined by interpretation of spectroscopic data.
