A C3-O-acylated analogue of achaetolide (2) was isolated from phytopathogenic fungus Helminthosporium velutinum TS28. The relative configuration involving the C3-O-acyl side chain was determined by NMR spectroscopic analysis combined with conformational analysis computer-assisted chemical shift calculations. The absolute configuration was established through ECD analysis after conversion into the dibenzoate (5).

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 1H NMR anal
