[摘要]:Clavicorolides A and B, two sesquiterpenoids possessing a novel backbone named as Clavicoronane-type, together with one new and two known Protoilludane-type sesquiterpenoids, namely, Tsugicolines M, Tsugicolines A , and Tsugicolines C, and Sterpurane, and Lactarane-type sesquiterpenoid Lactarorufin A, were isolated from the fermn. products of Clavicorona pyxidata YB2005. Their structures including relative and abs. configurations were elucidated on the basis of NMR data and anal. of X-ray single crystal diffraction. |
