Properties and stability
White needle-like crystals or crystalline powder (acetone), odorless. Stable in air. Mp239- 241℃, specific optical rotation [α]20D+164° (0.5%, acetone), [α]23D+169°(chloroform), [α]25D+208°-+217°(dioxane), ethanol of this product The solution has maximum absorption at a wavelength of 240nm. Easily soluble in chloroform (1:4), soluble in acetone (1:75), slightly soluble in ethanol and ether, and insoluble in water. This product dissolves in sulfuric acid and is yellow without fluorescence (different from hydrocortisone acetate).
Storage method
Shield from light and store in a sealed container.
Synthesis method
1. It is prepared by epoxidation, Wohlmann’s oxidation, mold oxidation, chromic acid oxidation, hydrogen bromide ring opening, Raney nickel catalytic debromination, iodination and acetoxy replacement of gestational dienolone;
2. Using progesterone acetate as raw material, 11-keto-16, 17α epoxy can be obtained through hydrogen oxide oxidation, Wohlmann’s oxidation, black rhizome biological oxidation, and chromic anhydride oxidation. Progesterone is obtained by ring-opening with hydrobromic acid, hydrodebromination to obtain cortisone, which reacts with iodine, reacts with molten potassium acetate to obtain a crude product, and finally recrystallizes.
Purpose
Biochemical research, adrenocortical hormone drugs, with anti-inflammatory and anti-allergic effects; intermediate of prednisone acetate. It is an anti-inflammatory agent in itself. It is used to treat adrenocortical hypofunction, rheumatoid arthritis, rheumatism, lupus erythematosus and other diseases.
