An improved method for the chemical synthesis of steroidal 20-oxo-21-oic acids.
A procedure is described for the chemical synthesis of steroidal-20-oxo-21-oic acids and -17 alpha(-hydroxy-20-oxo-21-oic acids. Corticosteroid derivatives containing the 20-oxo-21-aldehyde side chain are oxidized with freshly generated silver oxide in dilute aqueous sodium hydroxide.
