Abstract
The invention comprises: (a) 3b : 17a -dihydroxyallopregnane-11 : 20-dione; (b) the preparation thereof by a combination of the following steps (or the last one or more of them): (i) selectively reducing allopregnane-3 : 11 : 20-trione with hydrogen in the presence of Raney nickel catalyst to 3b -hydroxyallopregnane-11 : 20-dione, (ii) esterifying this with a fatty acid esterifying agent containing not more than 6 carbon atoms in the acyl group, (iii) treating the resulting ester with a fatty acid anhydride containing not more than 6 carbon atoms in the acyl group, in the presence of an aromatic sulphonic acid, to form the corresponding triacylate of D 11,17-allopregnadiene-3b : 11 : 20-triol, and (iv) treating this with an aromatic peracid followed by saponification; (c) treatment of (a) with bromine to produce its 21-bromo derivative; (d) treatment of the product of (c) with sodium iodide and potassium acetate to produce 3b : 17a -dihydroxy-21-acetoxyallopregnane-11 : 20-dione; (e) selective oxidation of the product of (d) with N-bromoacetamide in the presence of pyridine to 17a -hydroxy-21-acetoxyallopregnane-3 : 11 : 20-trione. In an example, step (i) is effected in a 1 : 1 mixture of ethanol and dioxane, step (ii) with acetic (or propionic) anhydride and pyridine, step (iii) with acetic anhydride in the presence of p-toluenesulphonic acid, step (iv) with perbenzoic acid in chloroform followed by methanolic caustic soda, process (c) with a solution of bromine in chloroform, and process (d) by refluxing in acetone. Specification 735,429 is referred to. Allopregnane-3 : 11 : 20-trione is prepared by shaking D 4 - pregnane - 3 : 11 : 20 - trione (11-ketoprogesterone) in an organic solvent (e.g. ethyl acetate) with hydrogen in the presence of a previously reduced 10 per cent palladiumcharcoal catalyst.
