Protection-Free One-Pot Synthesis of 2 '-Deoxynucleoside 5 '-Triphosphates and DNA Polymerization

[摘要]：By differentiating the functional groups on nucleosides, we have designed and developed a one-pot synthesis of deoxyribonucleoside 5'-triphosphates without any protection on the nucleosides. A facile synthesis is achieved by generating an in situ phosphitylating reagent that reacts selectively with the 5'-hydroxyl groups of the unprotected nucleosides. The synthesized triphosphates are of high quality and can be effectively incorporated into DNAs by DNA polymerase. This novel approach is straightforward and cost-effective for triphosphate synthesis.
