Abstract
The isolation of
'9-deacetoxyxenicin' [systematic name: (1R*,4aS*,7E,11aS*,1'R*,2'R*)-1-acetoxy-4-(1',2'-diacetoxy-4'-methylpent-3'-enyl)-7-methy1-11-methylene-1,4a,5,6,9,10,11,11a-octahydrocyclonona[c]pyran] (2) from Xenia
crassa and a further cyclized
diterpene (6) from Xenia viridis are described. The structure of (2) was derived
from n.m.r. spectroscopic comparison with xenicin (1),
whilst the structure of (6) was determined by a single-crystal X-ray analysis
when spectroscopy failed to afford an unambiguous structure.
