Abstract
Preparation procedure for 5 β -H-6-keto- Δ 7-14 α-hydroxysteroids of the partial formula ** (See formula) ** wherein R1 and R2 signify hydrogen or an alkyl or acyl moiety preferably lower or, when OR2 has configuration β, R1 and R2 together also mean an alkylene group, and wherein the substituent at position 3 may also be α or β-stable, characterized in that the corresponding 5 α -H-6-keto- Δ 7-14-dexosiesteroids are hydroxylated in the 5 β configuration; with selenium dioxide under simultaneous isomerization of the H 5 α atom, and then, if desired, the existing acyl residues are saponified, either the ether moieties or the alkylene moiety are dissociated or the free hydroxyl groups are acylated or etherified.
