 note = {3β-Acetoxy-5α-cholestan-6-one was prepared via several synthetic pathways from cholesterol. It was further converted into brmo-derivatives;5α-bromo-,5α,7α-dibromo-, and 5α,7β-dibromo-6-oxo compounds, in low yields by treatment with bromine in found that the C_5-bromo atom of the 3β-acetoxy-5α-bromocholestan-6-one rearranges to the C_7α position, but not to the C_7β position, by hydrogen bromide in acetic acid to give 7α-bromo-6-oxo compound. Stereochemical studies of these prepared α-bromo-6-oxo compounds were carried out by means of IR, NMR and ORD spectroscopic methods., 紀要論文},
