| titleOfInvention | PROCEDURE FOR OBTAINING 21-ALDEHIDOS OF THE SERIEPREGNANO. |
| abstract | Procedure for obtaining 21-aldehydes of the pregnant series, and derivatives thereof, of the formula **(See formula)** in which R1 and R2, each time, mean a free, esterified or ethereal hydroxy radical, or R1 together with R2 an oxo radical, characterized in that a) in a compound of the general formula **(See formula)** where R means a transformable moiety on the radical oxo 6 on the radical (see formula) or (see formula), the R moiety is transformed into these radicals, where R3 signifies an ethereal hydroxy radical, or b) in the compounds of formula **(See formula)** in which y have the meaning indicated in formula (I), in a manner known per se, a double bond is introduced at position 1, 2 or c) in the compounds of formula **(See formula)** Where R1 and R2 have the meaning indicated by formula (I) the radical 9β, 11β-epoxy dissociates with hydrofluoric acid or a hydrofluoric acid donor compound, and if desired, the compounds obtained from formula (1) in which (see formula) means a free oxo radical or at least one of the radicals R1, R2 means a free hydroxy radical, they are treated with esterifying or etherized agents, or the compounds of formula (I) in which at least one of radicals R1, R2 means an esterified or ethereal hydroxy radical are treated with hydrolyzing agents.
