Abstract:
A simple, straightforward, reliable, and efficient method for the chemical synthesis of sodium salt of 2'-deoxynucleoside-5'-O-triphosphates (dNTPs), starting from the corresponding nucleoside, is described. This improved "one-pot, three-step" synthetic strategy involves the monophosphorylation of nucleoside, followed by reaction with tributylammonium pyrophosphate and hydrolysis of the resulting cyclic intermediate to provide the corresponding dNTP in good yields (65% to 70%). It is noteworthy that the protocol holds good for both the purine deoxynucleotides, such as 2'-deoxyguanosine-5'-O-triphosphate (dGTP) and 2'-deoxyadenosine-5'-O-triphosphate (dATP), and pyrimidine deoxynucleotides, such as 2'-deoxycytidine-5'-O-triphosphate (dCTP), thymidine-5'-O-triphosphate (TTP), and 2'-deoxyuridine-5'-O-triphosphate (dUTP).

01:01Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.

01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
