| titleOfInvention | PROCEDURE FOR OBTAINING NEW PREGNAM 21-ALDE-HYDOS AND ITS DERIVATIVES. |
| abstract | Procedure for obtaining new pregnan-21-aldehydes and their derivatives of formula **(See formula)** where R1 and R2 together signify an oxo group or, in each case, a free, esterified or etherized hydroxy group, R3 signifies a free or esterized hydroxy group, R4 signifies an oxo group or a hydroxy group in position together with an atom of hydrogen and one of the residues R5 and R6 signifies a fluorine atom and the other hydrogen or a fluorine atom, characterized in that in a compound of formula **(See formula)** where R3, R5 and R6 have the meaning indicated above and R7 means an oxo group or a free or esterified hydroxyl group, in position, the CH2OH residue is transformed into the group (see formula) and the obtained 11β-acylates are hydrolyzed to the 11-hydroxy compounds, and if desired, the compounds obtained of formula (I), where R1 and R2 together form an oxo group or at least one of the R1 residues and R2 means a free hydroxy group, it is treated with esterifying or etherifying agents, or the compounds obtained of formula (I), where at least one of the residues R1 and R2 means an esterized or etherized hydroxy group, it is treated with hydrolyzing means, or in the obtained compounds, where R4 means a free hydroxy group, this is oxidized to the oxo group.
