摘要:
A method of preparing a thioic acid intermediate of fluticasone propionate includes: treating a 17β-[(N,N-dimethyl carbamoyl)thio]carbonyl compound in a solution including an alcohol and an alkali metal hydroxide, an alkaline-earth metal hydroxide, or a mixture thereof to cleave an amide from the 17β-[(N,N-dimethyl carbamoyl)thio]carbonyl compound; treating the solution to separate an aqueous portion; and adding an acid to the aqueous portion to obtain the thioic acid intermediate of fluticasone propionate. A method of preparing fluticasone propionate includes preparing the thioic acid intermediate of fluticasone propionate, and alkylating the thioic acid intermediate of fluticasone propionate to prepare the fluticasone propionate.

摘要:
The present invention provides an improved process for the preparation of 17-desoxy corticosteroid derivatives in a single chemical step by reacting the 17-hydroxy starting material with an excess of Trimethylsilyl Iodide. The present invention is specifically advantageous in preparing 17-desoxy corticosteroid derivatives having one or more halogen groups at positions 2, 6, 7 or 9 of the corticosteroid such as Clocortolone of Desoximetasone.

The invention is the compound 17.beta.-cyano-9.alpha., 17.alpha.-dihydroxyandrost-4-en-3-one (I) which is particularly useful as an intermediate in the production of the 17.alpha.-halo silyl ethers (II).
摘要:
Preparation of novel solvates of beclomethasone 17,21-dipropionate, by dissolution of beclomethasone 17,21-dipropionate in an ethereal or halogenated hydrocarbon solvent and precipitation by the addition of di-isopropyl ether. These new solvates are bulk stable, in both the micronized and non-micronized forms. The micronized form is especially suitable for the preparation of stable aerosol.
