A general synthesis of specifically deuterated nucleotides for studies of DNA and RNA

Abstract

An efficient procedure is described for the preparation of ribonucleotides and deoxyribonucleotides with deuterium incorporated at the 1', 4', or 5' position. Three intermediates-[1-2H]-D-ribose, [4-2H]-D-ribose, and [5-2H(2)]-D-ribose-were prepared by chemical synthesis and subsequently converted to ribonucleotides and deoxyribonucleotides via enzymatic reactions. Milligram quantities of the desired products were obtained with an average deuterium content of 96+/-1%.
