文摘Diacetyl derivative of hecogenin 1 was oxidized to unsaturated ketone 5 via allylicalcohol 3 when it reacted with dimethyldioxirane (DMDO). The structure of 3 was confirmed byX-ray crystal analysis and the highly regioselectivity of DMDO to different olefin bonds was alsoobserved when diosgenin derivative 6 was treated with DMDO.
