Ra. Davis et al., Longithorols C-E. Three new macrocyclic sesquiterpene hydroquinone metabolites from the Australian ascidian, Aplidium longithorax, J NAT PROD, 62(10), 1999, pp. 1405-1409
Chemical investigation of a Great Barrier Reef ascidian, Aplidium longithor
ax has resulted in the isolation of two new para-substituted cyclofarnesyla
ted hydroquinone compounds, longithorols C (1) and D (2), and a novel macro
cyclic chromenol, longithorol E (3). Longithorol C (1) had its absolute ste
reochemistry determined by the advanced Mosher method and all compounds had
their structures determined by interpretation of spectroscopic data.
