Reaktionsschritte

Cholesterol (20 g), methyl ethyl ketone (150 ml), and Girdler G65-S-RS catalyst (10.0 g) and 1-hexene (13 g) were heated and rocked at 250° C. for 4 hours. An analysis by gas chromatography indicated conversion to a mixture of 4-cholesten-3-one (78 parts), cholesterol (4 parts), coprostanone (8 parts), and cholestanone (6 parts). Similar results are obtained when sitosterol is used in place of cholesterol.
