A kind of method for preparing obeticholic acid intermediate and obeticholic acid |
| abstract |
The invention discloses a method for preparing an obeticholic acid intermediate and obeticholic acid, wherein the synthetic route of obeticholic acid is as follows The preparation method of the present invention has high conversion rate and stereoselectivity in the reaction process, and greatly reduces the difficulty of synthesizing obeticholic acid. The present invention has mild reaction conditions, is easy to realize industrially, and has easier controllable product purity and more efficient time efficiency; the raw materials used in the present invention are low in cost and safe, and while ensuring high-quality obeticholic acid, the production rate is effectively reduced. cost. |
