Manufacturing method for 2'-deoxynucleosides (dNus) has been developed using novel chemo-enzymatic process. The method consists of the chemical synthesis of 2'-deoxyribose 1-phosphate (dRP) and the enzymatic conversions of dRP into 2'-deoxyadenosine (dA), 2'-deoxyguanosine (dG) and 2'-deoxycytidine (dC). Large-scale preparation is successfully done, which demonstrates an applicability of this strategy to practical use. As thymidine is already under commercial-scale production, all four dNus are now ready for scale-up.
