Structures of two stereoisomers of a new type of indoloditerpene related to the tremorgenic mycotoxin paxilline, from Emericell desertorum and Emericella striata
The structure elucidation of emindoles DA (1) and SA (2), indoloditerpenesfrom the mycelial extract of Emericella desortorum and Emericellastriata, respectively, is reported, based on their 1H and 13C n.m.r. spectra and an X-ray crystallographic study of emindole DA monoacetate (4); these are novel proto-type indoloditerpenes biologically related to paxilline (3).
emindoles的结构解析DA(1)和SA(2)中,从菌丝体提取物indoloditerpenes裸胞壳desortorum和裸胞壳芨,分别报道,基于它们的1 H和13 C NMR谱和X的射线晶体学研究艾美达DA单乙酸盐(4); 这些是与Paxilline生物学相关的新型原型吲哚二萜(3)。
