✦ Synopsis

Abstract

The chromatographic behaviour of TLC on silica gel of 3 pairs of epimeric 3‐ethinyl‐3‐cholestanoles is described.

It is found that the k‐values of this class of compounds are predominantly influenced by the stereochemical orientation of the hydroxyl group. 3‐Ethinyl‐3‐cholestanoles with β‐configuration of the hydroxyl group have larger k‐values than their α‐oriented epimers.
