- 論文の詳細を見る
The stereochemistry of some dihydrofurano-isoflavones previously isolated from white lupin roots, or obtained following fungal metabolism of prenylated isoflavones, was investigated using CD spectroscopy. The osmate ester/pyridine complex of dextrorotatory lupinisoflavone A (1) exhibited a positive CD Cotton effect at 480 nm, indicating a side-structure configuration (S at C-2''), opposite to that of natural rotenone (9), which afforded a negative Cotton effect at 474 nm (R-configuration at C-2' on the sidestructure [ring E]). The stereochemistry of the laevorotatory luteone metabolite BC-1 (2) and lupinisoflavone D (4) (both R-configuration at C-2'') was similarly determined after converting to the corresponding dehydrate (10) or trimethyl-dehydrate (1b, 10a).
