3β-乙酰氧基甾-8-烯在染料和对硝基苯磺酰氯存在下被光氧化，得到Criegee重排产物3β-乙酰氧基-8，9-环氧-8，9-断链甾-7，9（11）-二烯（XV; R = Ac）和3β-乙酰氧基-7 α-氢过氧化甾-8-烯（VII; R = Ac）。这些化合物被认为是由3β-乙酰氧基-9 α-氢过氧甾-7-烯（II; R = Ac）产生的，并报道了它们的转化。（XV）中的桥连环癸-1，6-二烯体系参与跨环反应。
3β-Acetoxylanost-8-ene has been photo-oxygenated in the presence of a dye and p-nitrobenzenesulphonyl chloride to yield, among other products, the Criegee rearrangement product 3β-acetoxy-8,9-epoxy-8,9-secolanosta-7,9(11)-diene (XV; R = Ac) and 3β-acetoxy-7α-bydroperoxylanost-8-ene (VII; R = Ac). These ARE Thought to arise from 3β-acetoxy-9α-hydroperoxylanost-7-ene (II; R = Ac); their transformations are reported. The bridged cyclodeca-1,6-diene system in (XV) takes part in transannular reactions.
