Synthesis and IR. Spectroscopic Identification of Epimeric 3‐Ethinyl‐5α‐cholestan‐3‐ols The syntheses of the 3β‐ethinyl‐5α‐cholestan‐3α‐ols 2a, 2b, 2c and of the corresponding epimeric 3α‐ethinyl‐5 α‐cholestan‐3 β‐ols 3a, 3b, 3c are described. Bands at 1000 cm −1 for the α‐alcohols and at 1030 cm −1 for the β‐alcohols are found to be useful for the IR. spectroscopic identification of epimeric 3‐ethinyl‐5α‐cholestan‐3‐ols.
