Abstract
Procedure for the preparation of derivatives of 3, 6, 20-trioxo-pregnane of the general formula I: ** (formula-01) where D A is hydrogen or, provided that Y is (H, betaOH), A can be chlorine; B is hydrogen; X is hydrogen, fluorine, or chlorine; y is (H, BetaOH), or, provided X is chlorine, and can be (H, beta-chlorine); Q is hydroxy or Ov3 where V3 is an acyl radical of a hydrocarbon carboxylic acid that has up to 8 carbon atoms; M is CH2 OV 4, where V4 is hydrogen or an acyl radical of a hydrocarbon carboxylic acid having up to 8 carbon atoms; M is Ch2 Ov4, where V4 is hydrogen or an acyl radical of a hydrocarbon carboxylic acid having up to 8 carbon atoms; or Ov 4 together with Q is an alkylidenedioxy or alkylortoalkanoate group; it is (H, CH3), methylene, (H, alpha0V4) where V4 is as defined above, or together W and Q form an alkylidenedioxy group or grouping. ** (formula-02) ** where R and R1 are lower alkyl; or the grouping ** (formula-03) ** where R2 is lower alkyl or phenyl, characterized in that a compound of the general formula (VII). ** (formula-04) ** oxidizes in position 6.
