| titleOfInvention |
Process for the preparation of 6-keto steroids substituted in the 22-position from 20-formyl-6-keto-steroids of the pregnane series |
| abstract |
Compounds are of general formula (I):- where R1 = H or preferably lower alkyl or acyl group R2 = H or OH Z = H or CH3 Y = linear or branched alkyl or alkenyl (C is not 3) which may be substituted with free or functional derivatives of OH group or ethinyl group. C7......C8 is a saturated or unsaturated carbon--carbon bond is the A-ring in the steroid skeleton, and which may contain additional substituents in the molecule which are inert towards the reagent used indicates that the hydrogen atom at C-5, the methyl at C-21 and the OR1 substituent at C-22 may have the alpha- or beta-configuration Compounds are useful as chemical intermediates. |
