Herstellung von Cortexon‐Analogen mit konformativ fixierter Seitenkette Über Steroide. 235. Mitteilung

Preparation of Cortexon-Analogs with Conformatively Fixed Side Chain The synthesis of cortexon-analogs with a conformatively fixed side chain is described. The key step in the synthesis consists of an intramolecular displacement of bromine in position 21 by the oxygen of a 17α-hydroxymethyl group.
