A. Arnone et al., Tsugicoline E, a new polyoxygenated protoilludane sesquiterpene from the fungus Laurilia tsugicola, J NAT PROD, 62(1), 1999, pp. 51-53
Tsugicoline E (3) has been isolated from cultures of the Basidiomycetous fu
ngus Laurilia tsugicola and its structure deduced from H-1 and C-13 NMR and
single-crystal X-ray diffraction studies. The suggested absolute configura
tion is consistent with biogenetic considerations.
