Abstract
3β-Acetoxy-9α-hydroxy-5α-cholest-8(14)-en-15-one, 3β-acetoxy-8α,9α-epoxy-14α-hydroxy-5α-cholestan-15- one, and 3β-acetoxy-8α,9α-epoxy-14α-hydroxy-5α-cholestane- 11,15-dione were obtained by oxidizing 3β-acetoxy-5α-cholesta-8,14-diene with various amounts of Jones reagent or performing the reaction under different temperature conditions. The epoxy ketones were also obtained by independent synthesis.
