5β-Pregn-20-en-3α-ol, which is a key compound for the elucidation of reaction mechanism of pregnanediol 20-sulfate to D-homo-and Δ13-steroids by hot mineral acid, was derived from lithocholic acid by the degradation method of side chain. The overall yield of the desired product through these four steps from acetyllithocholic acid was 27%.
