The structures of viriditoxin, first isolated from Aspergillus & viridinutans as mycotoxin, and its derivatives, isolated from Paecilomyces variotii, were revised from 8, 8'-binaphtho-α-pyrone to 6, 6'-binaphtho-α-pyrone on the basis of spectroscopic investigations. The absolute stereochemistry of the 6, 6'-axis was also determined as an R-configuration.
根据光谱研究,从 8, 8'-binaphtho-α-pyrone 到 6, 6'-binaphtho-α-pyrone 的 viriditoxin 及其衍生物的结构进行了修订,这些衍生物最早是从曲霉和 viridinutans 中分离出来的霉菌毒素。6, 6'- 轴的绝对立体化学结构也被确定为 R-构型。
