制备方法与用途

地甾醇是一种类似于胆固醇的分子。桥甾醇则是胆固醇生物合成中的关键中间体，具体来说，它是胆固醇的直接前体，在布洛赫途径中扮演重要角色。作为内源性代谢产物，地甾醇广泛用于研究胆固醇代谢过程[1]。

  The present invention discloses a method for synthesizing 25-hydroxy cholesterol. The method is as below: subjecting 24-dehydrocholesterol derivative as a raw material, which undergoes an addition reaction with a hydroxyl containing reagent in an organic solvent under catalysis, and then hydrolyzing the reaction product and separating to obtain 25-hydroxy cholesterol. The present invention adopts hydroxyl containing reagents such as water, formic acid, acetic acid, propionic acid, butyric acid, benzoic acid, p-methyl benzoic acid to replace the commonly used extremely toxic reagents such as Cr reagent, Hg reagent and polyfluorinated acetone in the prior art. The raw materials of the present invention are easily available, and have low effect on environment. The operation and post treatment are convenient. Moreover, the method has the advantages of mild reaction conditions, simple operation, good selectivity, high efficiency, high yield, simple post treatment, easy product separation, less three wastes and easy industrialization.
