Abstract

NMR-guided fractionation of the lipophilic extract of filaments led to the isolation of a phenyl-containing chlorinated polyketide () and an alkyne-containing analogue (). Comparison of spectroscopic and spectrometric data of with the data of the previously reported trichotoxin, strongly suggested that these metabolites were identical and supports a structural revision of trichotoxin and its designation as trichotoxin A. In addition, we report the isolation and characterization of the alkyne-containing analogue trichotoxin B (). Absolute configuration of and is proposed based on spectroscopic comparison to a close structural analog.

摘要

核磁共振引导下对丝状真菌亲脂性提取物进行分级分离,得到了一种含苯基的氯化聚酮化合物()和一种含炔基的类似物()。将的光谱和光谱数据与先前报道的曲毒素的数据进行比较,强烈表明这些代谢产物是相同的,并支持对曲毒素的结构修订及其命名为曲毒素A。此外,我们报道了含炔基类似物曲毒素B()的分离和表征。基于与一种结构相近类似物的光谱比较,提出了和的绝对构型。
