| titleOfInvention | Process for the preparation of tetrahydrofolates |
| abstract | The invention relates to a new process for the preparation of 5,10-methenyl- (6R) -,n5-formyl- (6S) - and / or 5-methyl- (6S) -tetrahydrofolic acid and its salnzen, characterized in that one has an acid addition salt or the inner saltnof 5,10-methenyl- (6R, S) -tetrahydrofolic acid by diastereomer separationnsubjected to fractional crystallization and, if desired, the 5,10-Me obtainednthenyl- (6R) -tetrahydrofolic acid by treatment with a hydrolyzing agentnin 5-formyl- (6S) -tetrahydrofolic acid or by treatment with a reducing agentnAgent converted into 5-methyl- (6S) -tetrahydrofolic acid and / or a free one obtainednAcid converted into one of its salts by treatment with a base. |
