| titleOfInvention | Method for producing taurocholanic acid |
| abstract | (57) [Summary] (Modified) [Constitution] (a) In the presence of a tertiary amine, if desired, In a polar aprotic organic solvent that is miscible or partially miscible with water, formula (II): Cholanic acid represented by the formula (III): Treated with an acid chloride of formula (IV) and then (b) obtained formula (IV): The intermediate mixed acid anhydride of formula (I) is treated with taurine and then the resulting formula (I): A method for producing a taurocholanic acid derivative represented by the formula (I) or a salt thereof, comprising isolating the product represented by the formula (1) as it is or in the form of a salt thereof. [In the formula, A completes the 5β-cyclopentaneperhydrophenanthrene structure of colanic acid, and E represents hydrogen or methyl. R represents a hydrocarbon residue bonded to a carbonyl group by a tertiary carbon] [Effect] A taurocholanic acid derivative was obtained in high yield. |
