BILE ACID DERIVATIVES

The potassium permanganate oxidation of 3α, 12α-diacetoxy-24,24-diphenyl-Δ23-cholene yielded a new compound which was identified as 3α,12α-diacetoxy-23-keto-24-hydroxy-24,24-diphenylcholane. The latter steroid, on reduction with sodium borohydride, produced two isomeric glycols which were subsequently dehydrated to provide the corresponding 23-keto-24,24-diphenyl derivative.
