Metabolites of bird's nest fungi. Part 11. Diterpenoid metabolites of Cyathus earlei Lloyd

The bird's nest fungus Cyathusearlei Lloyd produces new diterpenoid metabolites of the cyathin type. Cyathatriol is shown to have structure 1 and has been correlated with cyathin A 3 . 11,15-O,O-Diacetylcyathatriol (2), 15-O-acetylcyathatriol (3), and 11-O-acetylcyathatriol (4) have also been i...

Description
Summary:The bird's nest fungus Cyathusearlei Lloyd produces new diterpenoid metabolites of the cyathin type. Cyathatriol is shown to have structure 1 and has been correlated with cyathin A 3 . 11,15-O,O-Diacetylcyathatriol (2), 15-O-acetylcyathatriol (3), and 11-O-acetylcyathatriol (4) have also been isolated. The first cyathins containing only two oxygens, cyathin B 2 (19) and allocyathin B 2 (12), are also described.
