title: Clavicorolides A and B, sesquiterpenoids from the fermentation products of edible fungus Clavicorona pyxidata.
abstract: Clavicorolides A (1) and B (2), two sesquiterpenoids possessing a novel backbone named as Clavicoronane-type, together with one new and two known Protoilludane-type sesquiterpenoids, namely, Tsugicolines M (3), A (4), and C (5), and Sterpurane (6), and Lactarane-type sesquiterpenoid Lactarorufin A (7), were isolated from the fermentation products of Clavicorona pyxidata YB2005. Their structures including relative and absolute configurations were elucidated on the basis of NMR data and analysis of X-ray single crystal diffraction.
