Abstract

The isolation and structure determination of neoallocyathin A 4 (10a) is described. Structures are proposed for cyathin A 4 (11) and cyathin C 5 (15). Methods for the transformation of cyathin A 3 into cyathin B 3 , allocyathin B 3 , and cyathin C 3 are reported. The isolation of glochidone (22) and ergosterol from the mycelium of Cyathushelenae is reported.
