摘要:
Achaetolide, as reported by Bodo et al. in 1983, was isolated from a fermentation broth of Ophiobolus sp. We established the absolute stereochemistry of achaetolide to be 3S,6R,7S,9R by way of relative stereochemical assignment with H-1 NMR analyses employing the corresponding acetonide, determination of C3 and C9 stereochemistries by an extended Mosher method.
