3β-acetoxy derivative, undergoes rearrangement with boron trifluoride to give the 5β-methyl-A-homo-B-nor-4a-ketone. The 3-deoxy-4a-ketone, however, undergoes a further rearrangement with boron trifluoride to give 5-methyl-5β-cholestan-6-one. 3β-Acetoxy-5,6β-epoxy-6α-methyl-5β-cholestane reacts rapidly with boron trifluoride to give a fluorohydrin, which suffers a slower rearrangement to give both the 5β-met
