| titleOfInvention | Method for producing 25-position hydroxide of cholesterols |
| abstract | (57) [Summary] [Structure] A method for producing 25-hydroxycholesterols, which comprises using a ruthenium compound as a catalyst in a reaction for converting a hydrogen atom at the 25-position of cholesterols to a hydroxyl group. [Effects] The present invention secures a large amount of starting materials at low cost in the industrial production of 25-hydroxylated cholesterols, which are useful as intermediates for the production of pharmaceuticals, greatly shortens the production process, and produces chemicals with high toxicity and risk. It is possible to avoid the use of water, improve the operability such as avoiding anhydrous conditions, drastically reduce the manufacturing equipment by shortening the process, and inevitably reduce the manufacturing cost. |
