Dienone–phenol type rearrangements. Part IV. 2-Hydroxy-3-oxo-Δ4-steroids
Abstract
The rearrangement of some steroidal hydroxy-cyclohexenones under a variety of acidic conditions has been studied. 2α-Hydroxy-cholest-4-en-3-ones give, in general, products with functionality at C-6 while C-2 becomes saturated. Enol acetates are also formed, but only one case of aromatisation was observed.
