Structure of a new type of indoloditerpenoid from Emericella purpurea
Abstract
The structure and relative stereochemistry of a new type of indoloditerpenoid designated as emindole PA 1, isolated from the mycelium of Emericella purpurea, along with the sesterterpene variecolin recently isolated from Emericella variecolor, has been confirmed by a chemical and spectroscopic investigation.
