5,7-Cholestadien-3 beta-ol was transformed into 14 beta-cholesta-5,7-dien-3 beta-ol in six steps. The inversion of the stereochemistry at C-14 was obtained by a selective protection of the delta 5 and the elaboration of the delta 7 double bond.

Abstract
5,7-Cholestadien-3 beta-ol was transformed into 14 beta-cholesta-5,7-dien-3 beta-ol in six steps. The inversion of the stereochemistry at C-14 was obtained by a selective protection of the delta 5 and the elaboration of the delta 7 double bond.
