【 摘 要 】
A diastereomeric mixture (55:45) of 3-oxo-23,24-dinorchol-4-en-22-hydroxy acids (4A and 4B) was synthesized from 3-oxo-23,24-dinorchol-4-en-22-al (1) in 3 steps. Similarly, 3-oxo-5β-cholane-24-hydroxy acid (9) was synthesized from 5β-cholane-3α,24-diol (5) in 4 steps. Full spectroscopic data for these compounds are presented.
