Citreobenzofurans A, B, and C, First Isolation of Sesquiterpene-Type Metabolites of a Hybrid Strain KO 0031 Derived from<i>Penicillium Citreo-viride</i>B. IFO 4692 and 6200
Three new sesquiterpene-type metabolites, citreobenzofurans A, B, and C, have been isolated ftrom the mycelium of the hybridstrainKO 0031 derivedfromPenicilliumcitreo-virideB. IFO4692 and 6200. Their stereostructures have been also elucidated on the basis of their spectral data.
三种新的倍半萜类代谢物,citreobenzofurans A、B 和 C,已从青霉绿青霉 B. IFO 4692 和 6200 杂交菌株 KO 0031 的菌丝体中分离出来。它们的立体结构也已在以下基础上阐明他们的光谱数据。

Phomenone, a known phytotoxic and mycotoxic sesquiterpene, afforded a new substituted benzofuran, by treatment with a H2SO4 in MeOH solution (10%). The structure of such compound, determined by spectroscopic and X-ray diffraction methods on its acetylderivative, is described. The formation mechanism of the new substituted benzofuran from the toxin is also discussed.
通过用H 2 SO 4的MeOH溶液(10%)处理,已知的植物毒性和霉菌性倍半萜烯Phomnone提供了新的取代苯并呋喃。描述了通过光谱和X射线衍射法对其乙酰基衍生物确定的这种化合物的结构。还讨论了由毒素形成新的取代苯并呋喃的机理。
