Abstract
3β-Acetoxy-8α,9α-epoxy-5α-cholestan-7-one in acetic acid under reflux gave 3β-acetoxy-5α-cholesta-8,14-dien-7-one. Under the same conditions. 3β-acetoxy-8α,14α-epoxy-5α- cholestan-7-one yieded 3β,6α-, 3β,15β-, and 3β,-15α-diacetoxy-5α-cholest-8(14)-en-7-one. The mechanism of formation of these products is discussed.
