3(β), 6(β)-Dihydroxy-allocholanic acid was prepared from hyode-soxycholic acid and succinylated at the C3-hydroxyl group. 3(β)-Hydroxy-Δ5-allocholenic acid was obtained from this succinylated compound by dehydrating the C3-hydroxyl group with POCl3 and hydrolysing the dehydration product with potassium hydroxide.
