摘要: Abstract 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 determined by NMR spectroscopic analysis combined with conformational computer-assisted chemical shift calculations. absolute established through ECD after conversion into dibenzoate (5).
