Objective:
To establish a new approach to synthesis and purification of calcium 5-formytetrahydrofolate.
Methods:
Target compound was synthesized by the use of folic acid as starting material via reduction, formylation, hydrolysis and salt formation
Results:
The structure of calcium 5-formytetrahydrofolate was confirmed by UV, 1H-NMR and elemental analysis and the overall yield was 54%-59%, 14%-17% higher than the reported yield.
Conclusion:
A convenient synthetic route was developed and it would be suitable for industrial production.
