The Absolute Structures of Dihydro- epiheveadride, as Characteristic Antifungal Agent against Filamentous Fungi, and Its Related Compounds from Unidentified Fungus IFM 52672
A newnonadride derivative, deoxoepiheveadride (2), was isolated along with dihydroepiheveadride (1), as a characteristic antifungal agent, from unidentified fungus IFM 52672. The absolute structures of 1 and 2 were elucidated by the spectroscopic and chemical investigation. The absolute configuration of heveadride (4), which had been isolated from Bipolaris heveae CBS 241.93, was also determined by
