The demand for 2'-deoxynucleosides is increasing rapidly in the fields of gene therapy, biological research, and medical diagnosis. Development of an efficient synthetic method has been expected over the past few decades. We developed a novel synthetic method applicable to industrial manufacture of all four natural 2'-deoxynucleosides. Chemically synthesized 2-deoxyribose 1-α-phosphate (dRP) was enzymatically converted to thymidine (T), 2'-deoxycytidine (dC), 2'-deoxyadenosine (dA), and 2'-deoxyguanosine (dG) in the presence of nucleoside phosphorylase. This chemo-enzymatic method consists of three distinctive technologies : (i) stereoselective synthesis of dRP by crystallization-induced asymmetric transformation; (ii) an efficient method to expedite enzymatic conversions by adding Mg (OH)2; (iii) development of a new enzyme for the enzymatic synthesis of dC.
